Starting a clustered database
To set up a clustered database (like Aurora), define a DatabaseCluster. You must always launch a database in a VPC. Use the vpcSubnets attribute to control whether your instances will be launched privately or publicly:
You must specify the instance to use as the writer, along with an optional list of readers (up to 15).

If there isn't a constant for the exact version you want to use, all of the Version classes have a static of method that can be used to create an arbitrary version.
ts
const customEngineVersion = rds.AuroraMysqlEngineVersion.of('5.7.mysql_aurora.2.08.1');
python
custom_engine_version = rds.AuroraMysqlEngineVersion.of("5.7.mysql_aurora.2.08.1")

go
customEngineVersion := rds.AuroraMysqlEngineVersion_Of(jsii.String("5.7.mysql_aurora.2.08.1"))
By default, the master password will be generated and stored in AWS Secrets Manager with auto-generated description.
Your cluster will be empty by default. To add a default database upon construction, specify the defaultDatabaseName attribute.
When you create a DB instance in your cluster, Aurora automatically chooses an appropriate AZ for that instance if you don't specify an AZ. You can place each instance in fixed availability zone by specifying availabilityZone property. For details, see Regions and Availability Zones.

If you want to issue read/write transactions directly on an Aurora Replica, you can use local write forwarding on Aurora MySQL and Aurora PostgreSQL. Local write forwarding allows read replicas to accept write transactions and forward them to the writer DB instance to be committed.
To enable local write forwarding, set the enableLocalWriteForwarding property to true:
ts
declare const vpc: ec2.IVpc;
new rds.DatabaseCluster(this, 'DatabaseCluster', {
engine: rds.DatabaseClusterEngine.auroraMysql({ version: rds.AuroraMysqlEngineVersion.VER_3_07_0 }),

Note: Local write forwarding is supported only for Aurora MySQL 3.04 or higher, and for Aurora PostgreSQL 16.4 or higher (for version 16), 15.8 or higher (for version 15), and 14.13 or higher (for version 14).
Use DatabaseClusterFromSnapshot to create a cluster from a snapshot:
ts
declare const vpc: ec2.Vpc;
new rds.DatabaseClusterFromSnapshot(this, 'Database', {

Writer: rds.ClusterInstance_Provisioned(jsii.String("writer")),
Vpc: Vpc,
SnapshotIdentifier: jsii.String("mySnapshot"),

By default, automatic minor version upgrades for the engine type are enabled in a cluster, but you can also disable this. To do so, set autoMinorVersionUpgrade to false.
ts
declare const vpc: ec2.IVpc;
new rds.DatabaseCluster(this, 'DatabaseCluster', {

Updating the database instances in a cluster
Database cluster instances may be updated in bulk or on a rolling basis.
An update to all instances in a cluster may cause significant downtime. To reduce the downtime, set the instanceUpdateBehavior property in DatabaseClusterBaseProps to InstanceUpdateBehavior.ROLLING. This adds a dependency between each instance so the update is performed on only one instance at a time.
Use InstanceUpdateBehavior.BULK to update all instances at once.
ts
declare const vpc: ec2.Vpc;
const cluster = new rds.DatabaseCluster(this, 'Database', {
engine: rds.DatabaseClusterEngine.auroraMysql({ version: rds.AuroraMysqlEngineVersion.VER_3_01_0 }),
writer: rds.ClusterInstance.provisioned('Instance', {

Serverless V2 instances in a Cluster
It is possible to create an RDS cluster with both serverlessV2 and provisioned instances. For example, this will create a cluster with a provisioned writer and a serverless v2 reader.
Note Before getting starting with this type of cluster it is highly recommended that you read through the Developer Guide which goes into much more detail on the things you need to take into consideration.

Monitoring
There are some CloudWatch metrics that are important for Aurora Serverless v2.
ServerlessDatabaseCapacity: An instance-level metric that can also be evaluated at the cluster level. At the cluster-level it represents the average capacity of all the instances in the cluster.ACUUtilization: Value of theServerlessDatabaseCapacity/ max ACU of the cluster.VolumeReadIOPs: Cluster-level metric that represents the average number of disk read I/O operations per second.VolumeWriteIOPs: Cluster-level metric that represents the average number of disk write I/O operations per second.ReadIOPS: Instance-level metric that represents the average read I/O operations per second. This metric is supported by DatabaseCluster and DatabaseClusterFromSnapshot both.WriteIOPS: Instance-level metric that represents the average write I/O operations per second. This metric is supported by DatabaseCluster and DatabaseClusterFromSnapshot both.

Capacity & Scaling
There are some things to take into consideration with Aurora Serverless v2.
To create a cluster that can support serverless v2 instances you configure a minimum and maximum capacity range on the cluster. This is an example showing the default values:
ts
declare const vpc: ec2.Vpc;
const cluster = new rds.DatabaseCluster(this, 'Database', {
engine: rds.DatabaseClusterEngine.auroraMysql({ version: rds.AuroraMysqlEngineVersion.VER_3_01_0 }),
writer: rds.ClusterInstance.serverlessV2('writer'),
serverlessV2MinCapacity: 0.5,
serverlessV2MaxCapacity: 2,
vpc,
});
python
# vpc: ec2.Vpc
cluster = rds.DatabaseCluster(self, "Database",
engine=rds.DatabaseClusterEngine.aurora_mysql(version=rds.AuroraMysqlEngineVersion.VER_3_01_0),
writer=rds.ClusterInstance.serverless_v2("writer"),
serverless_v2_min_capacity=0.5,
serverless_v2_max_capacity=2,
vpc=vpc
)
java
Vpc vpc;
DatabaseCluster cluster = DatabaseCluster.Builder.create(this, "Database")
.engine(DatabaseClusterEngine.auroraMysql(AuroraMysqlClusterEngineProps.builder().version(AuroraMysqlEngineVersion.VER_3_01_0).build()))
.writer(ClusterInstance.serverlessV2("writer"))
.serverlessV2MinCapacity(0.5)
.serverlessV2MaxCapacity(2)
.vpc(vpc)
.build();
csharp
Vpc vpc;
var cluster = new DatabaseCluster(this, "Database", new DatabaseClusterProps {
Engine = DatabaseClusterEngine.AuroraMysql(new AuroraMysqlClusterEngineProps { Version = AuroraMysqlEngineVersion.VER_3_01_0 }),
Writer = ClusterInstance.ServerlessV2("writer"),
ServerlessV2MinCapacity = 0.5,
ServerlessV2MaxCapacity = 2,
Vpc = vpc
});
go
var vpc Vpc
cluster := rds.NewDatabaseCluster(this, jsii.String("Database"), &DatabaseClusterProps{
Engine: rds.DatabaseClusterEngine_AuroraMysql(&AuroraMysqlClusterEngineProps{
Version: rds.AuroraMysqlEngineVersion_VER_3_01_0(),
}),
Writer: rds.ClusterInstance_ServerlessV2(jsii.String("writer")),
ServerlessV2MinCapacity: jsii.Number(0.5),
ServerlessV2MaxCapacity: jsii.Number(2),
Vpc: Vpc,
})
The capacity is defined as a number of Aurora capacity units (ACUs). You can specify in half-step increments (40, 40.5, 41, etc). Each serverless instance in the cluster inherits the capacity that is defined on the cluster. It is not possible to configure separate capacity at the instance level.
The maximum capacity is mainly used for budget control since it allows you to set a cap on how high your instance can scale.
The minimum capacity is a little more involved. This controls a couple different things.
- The scale-up rate is proportional to the current capacity (larger instances scale up faster)
- Adjust the minimum capacity to obtain a suitable scaling rate
- Network throughput is proportional to capacity
Info More complete details can be found in the docs
You can also set minimum capacity to zero ACUs and automatically pause, if they don't have any connections initiated by user activity within a time period specified by serverlessV2AutoPauseDuration (300 seconds by default). For more information, see Scaling to Zero ACUs with automatic pause and resume for Aurora Serverless v2.
ts
declare const vpc: ec2.Vpc;
const cluster = new rds.DatabaseCluster(this, 'Database', {
engine: rds.DatabaseClusterEngine.auroraMysql({ version: rds.AuroraMysqlEngineVersion.VER_3_08_0 }),
writer: rds.ClusterInstance.serverlessV2('writer'),
serverlessV2MinCapacity: 0,
serverlessV2AutoPauseDuration: Duration.hours(1),
vpc,
});
python
# vpc: ec2.Vpc
cluster = rds.DatabaseCluster(self, "Database",
engine=rds.DatabaseClusterEngine.aurora_mysql(version=rds.AuroraMysqlEngineVersion.VER_3_08_0),
writer=rds.ClusterInstance.serverless_v2("writer"),
serverless_v2_min_capacity=0,
serverless_v2_auto_pause_duration=Duration.hours(1),
vpc=vpc
)
java
Vpc vpc;
DatabaseCluster cluster = DatabaseCluster.Builder.create(this, "Database")
.engine(DatabaseClusterEngine.auroraMysql(AuroraMysqlClusterEngineProps.builder().version(AuroraMysqlEngineVersion.VER_3_08_0).build()))
.writer(ClusterInstance.serverlessV2("writer"))
.serverlessV2MinCapacity(0)
.serverlessV2AutoPauseDuration(Duration.hours(1))
.vpc(vpc)
.build();
csharp
Vpc vpc;
var cluster = new DatabaseCluster(this, "Database", new DatabaseClusterProps {
Engine = DatabaseClusterEngine.AuroraMysql(new AuroraMysqlClusterEngineProps { Version = AuroraMysqlEngineVersion.VER_3_08_0 }),
Writer = ClusterInstance.ServerlessV2("writer"),
ServerlessV2MinCapacity = 0,
ServerlessV2AutoPauseDuration = Duration.Hours(1),
Vpc = vpc
});
go
var vpc Vpc
cluster := rds.NewDatabaseCluster(this, jsii.String("Database"), &DatabaseClusterProps{
Engine: rds.DatabaseClusterEngine_AuroraMysql(&AuroraMysqlClusterEngineProps{
Version: rds.AuroraMysqlEngineVersion_VER_3_08_0(),
}),
Writer: rds.ClusterInstance_ServerlessV2(jsii.String("writer")),
ServerlessV2MinCapacity: jsii.Number(0),
ServerlessV2AutoPauseDuration: awscdk.Duration_Hours(jsii.Number(1)),
Vpc: Vpc,
})
Another way that you control the capacity/scaling of your serverless v2 reader instances is based on the promotion tier which can be between 0-15. Any serverless v2 instance in the 0-1 tiers will scale alongside the writer even if the current read load does not require the capacity. This is because instances in the 0-1 tier are first priority for failover and Aurora wants to ensure that in the event of a failover the reader that gets promoted is scaled to handle the write load.
ts
declare const vpc: ec2.Vpc;
const cluster = new rds.DatabaseCluster(this, 'Database', {
engine: rds.DatabaseClusterEngine.auroraMysql({ version: rds.AuroraMysqlEngineVersion.VER_3_01_0 }),
writer: rds.ClusterInstance.serverlessV2('writer'),
readers: [
// will be put in promotion tier 1 and will scale with the writer
rds.ClusterInstance.serverlessV2('reader1', { scaleWithWriter: true }),
// will be put in promotion tier 2 and will not scale with the writer
rds.ClusterInstance.serverlessV2('reader2'),
],
vpc,
});
python
# vpc: ec2.Vpc
cluster = rds.DatabaseCluster(self, "Database",
engine=rds.DatabaseClusterEngine.aurora_mysql(version=rds.AuroraMysqlEngineVersion.VER_3_01_0),
writer=rds.ClusterInstance.serverless_v2("writer"),
readers=[
# will be put in promotion tier 1 and will scale with the writer
rds.ClusterInstance.serverless_v2("reader1", scale_with_writer=True),
# will be put in promotion tier 2 and will not scale with the writer
rds.ClusterInstance.serverless_v2("reader2")
],
vpc=vpc
)
java
Vpc vpc;
DatabaseCluster cluster = DatabaseCluster.Builder.create(this, "Database")
.engine(DatabaseClusterEngine.auroraMysql(AuroraMysqlClusterEngineProps.builder().version(AuroraMysqlEngineVersion.VER_3_01_0).build()))
.writer(ClusterInstance.serverlessV2("writer"))
.readers(List.of(ClusterInstance.serverlessV2("reader1", ServerlessV2ClusterInstanceProps.builder().scaleWithWriter(true).build()), ClusterInstance.serverlessV2("reader2")))
.vpc(vpc)
.build();
csharp
Vpc vpc;
var cluster = new DatabaseCluster(this, "Database", new DatabaseClusterProps {
Engine = DatabaseClusterEngine.AuroraMysql(new AuroraMysqlClusterEngineProps { Version = AuroraMysqlEngineVersion.VER_3_01_0 }),
Writer = ClusterInstance.ServerlessV2("writer"),
Readers = new [] { ClusterInstance.ServerlessV2("reader1", new ServerlessV2ClusterInstanceProps { ScaleWithWriter = true }), ClusterInstance.ServerlessV2("reader2") },
Vpc = vpc
});
go
var vpc Vpc
cluster := rds.NewDatabaseCluster(this, jsii.String("Database"), &DatabaseClusterProps{
Engine: rds.DatabaseClusterEngine_AuroraMysql(&AuroraMysqlClusterEngineProps{
Version: rds.AuroraMysqlEngineVersion_VER_3_01_0(),
}),
Writer: rds.ClusterInstance_ServerlessV2(jsii.String("writer")),
Readers: []IClusterInstance{
rds.ClusterInstance_*ServerlessV2(jsii.String("reader1"), &ServerlessV2ClusterInstanceProps{
ScaleWithWriter: jsii.Boolean(true),
}),
rds.ClusterInstance_*ServerlessV2(jsii.String("reader2")),
},
Vpc: Vpc,
})
- When the writer scales up, any readers in tier 0-1 will scale up to match
- Scaling for tier 2-15 is independent of what is happening on the writer
- Readers in tier 2-15 scale up based on read load against the individual reader
When configuring your cluster it is important to take this into consideration and ensure that in the event of a failover there is an instance that is scaled up to take over.
Mixing Serverless v2 and Provisioned instances
You are able to create a cluster that has both provisioned and serverless instances. This blog post has an excellent guide on choosing between serverless and provisioned instances based on use case.
There are a couple of high level differences:
- Engine Version (serverless only supports MySQL 8+ & PostgreSQL 13+)
- Memory up to 256GB can be supported by serverless
Provisioned writer
With a provisioned writer and serverless v2 readers, some of the serverless readers will need to be configured to scale with the writer so they can act as failover targets. You will need to determine the correct capacity based on the provisioned instance type and its utilization.
As an example, if the CPU utilization for a db.r6g.4xlarge (128 GB) instance stays at 10% most times, then the minimum ACUs may be set at 6.5 ACUs (10% of 128 GB) and maximum may be set at 64 ACUs (64x2GB=128GB). Keep in mind that the speed at which the serverless instance can scale up is determined by the minimum capacity so if your cluster has spiky workloads you may need to set a higher minimum capacity.
ts
declare const vpc: ec2.Vpc;
const cluster = new rds.DatabaseCluster(this, 'Database', {
engine: rds.DatabaseClusterEngine.auroraMysql({ version: rds.AuroraMysqlEngineVersion.VER_3_01_0 }),

serverlessV2MinCapacity: 6.5,
serverlessV2MaxCapacity: 64,
readers: [
// will be put in promotion tier 1 and will scale with the writer
rds.ClusterInstance.serverlessV2('reader1', { scaleWithWriter: true }),
// will be put in promotion tier 2 and will not scale with the writer

ScaleWithWriter: jsii.Boolean(true),
}),
rds.ClusterInstance_*ServerlessV2(jsii.String("reader2")),
},
Vpc: Vpc,
})
In the above example reader1 will scale with the writer based on the writer's utilization. So if the writer were to go to 50% utilization then reader1 would scale up to use 32 ACUs. If the read load stayed consistent then reader2 may remain at 6.5 since it is not configured to scale with the writer.
If one of your Aurora Serverless v2 DB instances consistently reaches the limit of its maximum capacity, Aurora indicates this condition by setting the DB instance to a status of incompatible-parameters. While the DB instance has the incompatible-parameters status, some operations are blocked. For example, you can't upgrade the engine version.
CA certificate
Use the caCertificate property to specify the CA certificates to use for a cluster instances:
ts
declare const vpc: ec2.Vpc;
const cluster = new rds.DatabaseCluster(this, 'Database', {
engine: rds.DatabaseClusterEngine.auroraMysql({ version: rds.AuroraMysqlEngineVersion.VER_3_01_0 }),

Until RDS applies the changes, the DB instance remains in a drift state. As a result, the configuration doesn't fully reflect the requested modifications and temporarily diverges from the intended state.
Currently, CloudFormation does not support to schedule modifications of the cluster configurations. To apply changes of the cluster, such as engine version, in the next scheduled maintenance window, you should use modify-db-cluster CLI command or management console.
For details, see Modifying an Amazon Aurora DB cluster.
Retaining Automated Backups
By default, when a database cluster is deleted, automated backups are removed immediately unless an AWS Backup policy specifies a point-in-time restore rule. You can control this behavior using the deleteAutomatedBackups property:
ts
declare const vpc: ec2.IVpc;
// Retain automated backups after cluster deletion
new rds.DatabaseCluster(this, 'Database', {
engine: rds.DatabaseClusterEngine.auroraMysql({ version: rds.AuroraMysqlEngineVersion.VER_3_01_0 }),
writer: rds.ClusterInstance.provisioned('writer'),
vpc,
deleteAutomatedBackups: false,
});
python
# vpc: ec2.IVpc
# Retain automated backups after cluster deletion
rds.DatabaseCluster(self, "Database",
engine=rds.DatabaseClusterEngine.aurora_mysql(version=rds.AuroraMysqlEngineVersion.VER_3_01_0),
writer=rds.ClusterInstance.provisioned("writer"),
vpc=vpc,
delete_automated_backups=False
)
java
IVpc vpc;
// Retain automated backups after cluster deletion
// Retain automated backups after cluster deletion
DatabaseCluster.Builder.create(this, "Database")
.engine(DatabaseClusterEngine.auroraMysql(AuroraMysqlClusterEngineProps.builder().version(AuroraMysqlEngineVersion.VER_3_01_0).build()))
.writer(ClusterInstance.provisioned("writer"))
.vpc(vpc)
.deleteAutomatedBackups(false)
.build();
csharp
IVpc vpc;
// Retain automated backups after cluster deletion
// Retain automated backups after cluster deletion
new DatabaseCluster(this, "Database", new DatabaseClusterProps {
Engine = DatabaseClusterEngine.AuroraMysql(new AuroraMysqlClusterEngineProps { Version = AuroraMysqlEngineVersion.VER_3_01_0 }),
Writer = ClusterInstance.Provisioned("writer"),
Vpc = vpc,
DeleteAutomatedBackups = false
});
go
var vpc IVpc
// Retain automated backups after cluster deletion
// Retain automated backups after cluster deletion
rds.NewDatabaseCluster(this, jsii.String("Database"), &DatabaseClusterProps{
Engine: rds.DatabaseClusterEngine_AuroraMysql(&AuroraMysqlClusterEngineProps{
Version: rds.AuroraMysqlEngineVersion_VER_3_01_0(),
}),
Writer: rds.ClusterInstance_Provisioned(jsii.String("writer")),
Vpc: Vpc,
DeleteAutomatedBackups: jsii.Boolean(false),
})
When set to false, automated backups are retained according to the configured retention period after the cluster is deleted. When set to true or not specified (default), automated backups are deleted immediately when the cluster is deleted. Detail about this feature can be found in the AWS documentation.
Migrating from instanceProps
Creating instances in a DatabaseCluster using instanceProps & instances is deprecated. To migrate to the new properties you can provide the isFromLegacyInstanceProps property.
For example, in order to migrate from this deprecated config:
ts
declare const vpc: ec2.Vpc;
const cluster = new rds.DatabaseCluster(this, 'Database', {
engine: rds.DatabaseClusterEngine.auroraMysql({
version: rds.AuroraMysqlEngineVersion.VER_3_03_0,
}),
instances: 2,
instanceProps: {
instanceType: ec2.InstanceType.of(ec2.InstanceClass.BURSTABLE3, ec2.InstanceSize.SMALL),
vpcSubnets: { subnetType: ec2.SubnetType.PUBLIC },
vpc,
},
});
python
# vpc: ec2.Vpc
cluster = rds.DatabaseCluster(self, "Database",
engine=rds.DatabaseClusterEngine.aurora_mysql(
version=rds.AuroraMysqlEngineVersion.VER_3_03_0
),
instances=2,
instance_props=rds.InstanceProps(
instance_type=ec2.InstanceType.of(ec2.InstanceClass.BURSTABLE3, ec2.InstanceSize.SMALL),
vpc_subnets=ec2.SubnetSelection(subnet_type=ec2.SubnetType.PUBLIC),
vpc=vpc
)
)
java
Vpc vpc;
DatabaseCluster cluster = DatabaseCluster.Builder.create(this, "Database")
.engine(DatabaseClusterEngine.auroraMysql(AuroraMysqlClusterEngineProps.builder()
.version(AuroraMysqlEngineVersion.VER_3_03_0)
.build()))
.instances(2)
.instanceProps(InstanceProps.builder()
.instanceType(InstanceType.of(InstanceClass.BURSTABLE3, InstanceSize.SMALL))
.vpcSubnets(SubnetSelection.builder().subnetType(SubnetType.PUBLIC).build())
.vpc(vpc)
.build())
.build();
csharp
Vpc vpc;
var cluster = new DatabaseCluster(this, "Database", new DatabaseClusterProps {
Engine = DatabaseClusterEngine.AuroraMysql(new AuroraMysqlClusterEngineProps {
Version = AuroraMysqlEngineVersion.VER_3_03_0
}),
Instances = 2,
InstanceProps = new InstanceProps {
InstanceType = InstanceType.Of(InstanceClass.BURSTABLE3, InstanceSize.SMALL),
VpcSubnets = new SubnetSelection { SubnetType = SubnetType.PUBLIC },
Vpc = vpc
}
});
go
var vpc Vpc
cluster := rds.NewDatabaseCluster(this, jsii.String("Database"), &DatabaseClusterProps{
Engine: rds.DatabaseClusterEngine_AuroraMysql(&AuroraMysqlClusterEngineProps{
Version: rds.AuroraMysqlEngineVersion_VER_3_03_0(),
}),
Instances: jsii.Number(2),
InstanceProps: &InstanceProps{
InstanceType: ec2.InstanceType_Of(ec2.InstanceClass_BURSTABLE3, ec2.InstanceSize_SMALL),
VpcSubnets: &SubnetSelection{
SubnetType: ec2.SubnetType_PUBLIC,
},
Vpc: *Vpc,
},
})
You would need to migrate to this. The old method of providing instanceProps and instances will create the number of instances that you provide. The first instance will be the writer and the rest will be the readers. It's important that the id that you provide is Instance{NUMBER}. The writer should always be Instance1 and the readers will increment from there.
Make sure to run a cdk diff before deploying to make sure that all changes are expected. Always test the migration in a non-production environment first.

Creating a read replica cluster
Use replicationSourceIdentifier to create a read replica cluster:
ts
declare const vpc: ec2.Vpc;
declare const primaryCluster: rds.DatabaseCluster;
new rds.DatabaseCluster(this, 'DatabaseCluster', {
engine: rds.DatabaseClusterEngine.auroraMysql({
version: rds.AuroraMysqlEngineVersion.VER_3_03_0,
}),
writer: rds.ClusterInstance.serverlessV2('Writer'),
vpc,
replicationSourceIdentifier: primaryCluster.clusterArn,
});
python
# vpc: ec2.Vpc
# primary_cluster: rds.DatabaseCluster
rds.DatabaseCluster(self, "DatabaseCluster",
engine=rds.DatabaseClusterEngine.aurora_mysql(
version=rds.AuroraMysqlEngineVersion.VER_3_03_0
),
writer=rds.ClusterInstance.serverless_v2("Writer"),
vpc=vpc,
replication_source_identifier=primary_cluster.cluster_arn
)
java
Vpc vpc;
DatabaseCluster primaryCluster;
DatabaseCluster.Builder.create(this, "DatabaseCluster")
.engine(DatabaseClusterEngine.auroraMysql(AuroraMysqlClusterEngineProps.builder()
.version(AuroraMysqlEngineVersion.VER_3_03_0)
.build()))
.writer(ClusterInstance.serverlessV2("Writer"))
.vpc(vpc)
.replicationSourceIdentifier(primaryCluster.getClusterArn())
.build();
csharp
Vpc vpc;
DatabaseCluster primaryCluster;
new DatabaseCluster(this, "DatabaseCluster", new DatabaseClusterProps {
Engine = DatabaseClusterEngine.AuroraMysql(new AuroraMysqlClusterEngineProps {
Version = AuroraMysqlEngineVersion.VER_3_03_0
}),
Writer = ClusterInstance.ServerlessV2("Writer"),
Vpc = vpc,
ReplicationSourceIdentifier = primaryCluster.ClusterArn
});
go
var vpc Vpc
var primaryCluster DatabaseCluster
rds.NewDatabaseCluster(this, jsii.String("DatabaseCluster"), &DatabaseClusterProps{
Engine: rds.DatabaseClusterEngine_AuroraMysql(&AuroraMysqlClusterEngineProps{
Version: rds.AuroraMysqlEngineVersion_VER_3_03_0(),
}),
Writer: rds.ClusterInstance_ServerlessV2(jsii.String("Writer")),
Vpc: Vpc,
ReplicationSourceIdentifier: primaryCluster.clusterArn,
})
Note: Cannot create a read replica cluster with credentials as the value is inherited from the source DB cluster.
Starting an instance database
To set up an instance database, define a DatabaseInstance. You must always launch a database in a VPC. Use the vpcSubnets attribute to control whether your instances will be launched privately or publicly:
ts
declare const vpc: ec2.Vpc;
const instance = new rds.DatabaseInstance(this, 'Instance', {
engine: rds.DatabaseInstanceEngine.oracleSe2({ version: rds.OracleEngineVersion.VER_19_0_0_0_2020_04_R1 }),
// optional, defaults to m5.large
instanceType: ec2.InstanceType.of(ec2.InstanceClass.BURSTABLE3, ec2.InstanceSize.SMALL),
credentials: rds.Credentials.fromGeneratedSecret('syscdk'), // Optional - will default to 'admin' username and generated password
vpc,
vpcSubnets: {
subnetType: ec2.SubnetType.PRIVATE_WITH_EGRESS,
}
});
python
# vpc: ec2.Vpc
instance = rds.DatabaseInstance(self, "Instance",
engine=rds.DatabaseInstanceEngine.oracle_se2(version=rds.OracleEngineVersion.VER_19_0_0_0_2020_04_R1),
# optional, defaults to m5.large
instance_type=ec2.InstanceType.of(ec2.InstanceClass.BURSTABLE3, ec2.InstanceSize.SMALL),
credentials=rds.Credentials.from_generated_secret("syscdk"), # Optional - will default to 'admin' username and generated password
vpc=vpc,
vpc_subnets=ec2.SubnetSelection(
subnet_type=ec2.SubnetType.PRIVATE_WITH_EGRESS
)
)
java
Vpc vpc;
DatabaseInstance instance = DatabaseInstance.Builder.create(this, "Instance")
.engine(DatabaseInstanceEngine.oracleSe2(OracleSe2InstanceEngineProps.builder().version(OracleEngineVersion.VER_19_0_0_0_2020_04_R1).build()))
// optional, defaults to m5.large
.instanceType(InstanceType.of(InstanceClass.BURSTABLE3, InstanceSize.SMALL))
.credentials(Credentials.fromGeneratedSecret("syscdk")) // Optional - will default to 'admin' username and generated password
.vpc(vpc)
.vpcSubnets(SubnetSelection.builder()
.subnetType(SubnetType.PRIVATE_WITH_EGRESS)
.build())
.build();
csharp
Vpc vpc;
var instance = new DatabaseInstance(this, "Instance", new DatabaseInstanceProps {
Engine = DatabaseInstanceEngine.OracleSe2(new OracleSe2InstanceEngineProps { Version = OracleEngineVersion.VER_19_0_0_0_2020_04_R1 }),
// optional, defaults to m5.large
InstanceType = InstanceType.Of(InstanceClass.BURSTABLE3, InstanceSize.SMALL),
Credentials = Credentials.FromGeneratedSecret("syscdk"), // Optional - will default to 'admin' username and generated password
Vpc = vpc,
VpcSubnets = new SubnetSelection {
SubnetType = SubnetType.PRIVATE_WITH_EGRESS
}
});
go
var vpc Vpc
instance := rds.NewDatabaseInstance(this, jsii.String("Instance"), &DatabaseInstanceProps{

}),
// optional, defaults to m5.large
InstanceType: ec2.InstanceType_Of(ec2.InstanceClass_BURSTABLE3, ec2.InstanceSize_SMALL),

// Optional - will default to 'admin' username and generated password
Vpc: Vpc,
VpcSubnets: &SubnetSelection{
SubnetType: ec2.SubnetType_PRIVATE_WITH_EGRESS,

If there isn't a constant for the exact engine version you want to use, all of the Version classes have a static of method that can be used to create an arbitrary version.
ts
const customEngineVersion = rds.OracleEngineVersion.of('19.0.0.0.ru-2020-04.rur-2020-04.r1', '19');
python
custom_engine_version = rds.OracleEngineVersion.of("19.0.0.0.ru-2020-04.rur-2020-04.r1", "19")
java
OracleEngineVersion customEngineVersion = OracleEngineVersion.of("19.0.0.0.ru-2020-04.rur-2020-04.r1", "19");
csharp
var customEngineVersion = OracleEngineVersion.Of("19.0.0.0.ru-2020-04.rur-2020-04.r1", "19");
go
customEngineVersion := rds.OracleEngineVersion_Of(jsii.String("19.0.0.0.ru-2020-04.rur-2020-04.r1"), jsii.String("19"))
By default, the master password will be generated and stored in AWS Secrets Manager.
To use the storage auto scaling option of RDS you can specify the maximum allocated storage. This is the upper limit to which RDS can automatically scale the storage. More info can be found here Example for max storage configuration:
ts
declare const vpc: ec2.Vpc;
const instance = new rds.DatabaseInstance(this, 'Instance', {
engine: rds.DatabaseInstanceEngine.postgres({ version: rds.PostgresEngineVersion.VER_16_3 }),
// optional, defaults to m5.large
instanceType: ec2.InstanceType.of(ec2.InstanceClass.BURSTABLE2, ec2.InstanceSize.SMALL),
vpc,
maxAllocatedStorage: 200,
});
python
# vpc: ec2.Vpc

To use dual-stack mode, specify NetworkType.DUAL on the networkType property:
ts
declare const vpc: ec2.Vpc; // VPC and subnets must have IPv6 CIDR blocks

Automatic backups of read replica instances are only supported for MySQL and MariaDB. By default, automatic backups are disabled for read replicas and can only be enabled (using backupRetention) if also enabled on the source instance.
For more information on configuring Oracle database instances, see option groups and parameter groups.
Use the storageType property to specify the type of storage to use for the instance:

Use the caCertificate property to specify the CA certificates to use for the instance:
ts
declare const vpc: ec2.Vpc;
new rds.DatabaseInstance(this, 'Instance', {
engine: rds.DatabaseInstanceEngine.mysql({ version: rds.MysqlEngineVersion.VER_8_0_39 }),

Scheduling modifications
To schedule modifications in the next scheduled maintenance window, specify applyImmediately to false:
ts
declare const vpc: ec2.Vpc;
new rds.DatabaseInstance(this, 'Instance', {
engine: rds.DatabaseInstanceEngine.mysql({ version: rds.MysqlEngineVersion.VER_8_0_39 }),
vpc,
applyImmediately: false,
});
python
# vpc: ec2.Vpc
rds.DatabaseInstance(self, "Instance",
engine=rds.DatabaseInstanceEngine.mysql(version=rds.MysqlEngineVersion.VER_8_0_39),
vpc=vpc,
apply_immediately=False
)
java
Vpc vpc;
DatabaseInstance.Builder.create(this, "Instance")
.engine(DatabaseInstanceEngine.mysql(MySqlInstanceEngineProps.builder().version(MysqlEngineVersion.VER_8_0_39).build()))
.vpc(vpc)
.applyImmediately(false)
.build();
csharp
Vpc vpc;
new DatabaseInstance(this, "Instance", new DatabaseInstanceProps {
Engine = DatabaseInstanceEngine.Mysql(new MySqlInstanceEngineProps { Version = MysqlEngineVersion.VER_8_0_39 }),
Vpc = vpc,
ApplyImmediately = false
});
go
var vpc Vpc
rds.NewDatabaseInstance(this, jsii.String("Instance"), &DatabaseInstanceProps{
Engine: rds.DatabaseInstanceEngine_Mysql(&MySqlInstanceEngineProps{
Version: rds.MysqlEngineVersion_VER_8_0_39(),
}),
Vpc: Vpc,
ApplyImmediately: jsii.Boolean(false),
})
Until RDS applies the changes, the DB instance remains in a drift state. As a result, the configuration doesn't fully reflect the requested modifications and temporarily diverges from the intended state.
For details, see Using the schedule modifications setting.
Setting Public Accessibility
You can set public accessibility for the DatabaseInstance or the ClusterInstance using the publiclyAccessible property. If you specify true, it creates an instance with a publicly resolvable DNS name, which resolves to a public IP address. If you specify false, it creates an internal instance with a DNS name that resolves to a private IP address.
The default value will be true if vpcSubnets is subnetType: SubnetType.PUBLIC, false otherwise. In the case of a cluster, the default value will be determined on the vpc placement of the DatabaseCluster otherwise it will be determined based on the vpc placement of standalone DatabaseInstance.
ts
declare const vpc: ec2.Vpc;

Instance events
To define Amazon CloudWatch event rules for database instances, use the onEvent method:
ts
declare const instance: rds.DatabaseInstance;
declare const fn: lambda.Function;
const rule = instance.onEvent('InstanceEvent', { target: new targets.LambdaFunction(fn) });
python
# instance: rds.DatabaseInstance
# fn: lambda.Function
rule = instance.on_event("InstanceEvent", target=targets.LambdaFunction(fn))
java
DatabaseInstance instance;
Function fn;
Rule rule = instance.onEvent("InstanceEvent", OnEventOptions.builder().target(new LambdaFunction(fn)).build());
csharp
DatabaseInstance instance;
Function fn;
var rule = instance.OnEvent("InstanceEvent", new OnEventOptions { Target = new LambdaFunction(fn) });
go
var instance DatabaseInstance
var fn Function
rule := instance.OnEvent(jsii.String("InstanceEvent"), &OnEventOptions{
Target: targets.NewLambdaFunction(fn),
})
Login credentials
By default, database instances and clusters (with the exception of DatabaseInstanceFromSnapshot and ServerlessClusterFromSnapshot) will have admin user with an auto-generated password. An alternative username (and password) may be specified for the admin user instead of the default.
The following examples use a DatabaseInstance, but the same usage is applicable to DatabaseCluster.
ts

RDS-managed master password
You can enable RDS to manage the master password in AWS Secrets Manager by setting manageMasterUserPassword to true. When enabled, RDS creates and manages the secret automatically, and you can only specify the username and optionally an encryptionKey in the credentials:
ts

declare const kmsKey: kms.Key;
// Database cluster with RDS-managed password
new rds.DatabaseCluster(this, 'Cluster', {
engine: rds.DatabaseClusterEngine.auroraMysql({ version: rds.AuroraMysqlEngineVersion.VER_3_01_0 }),

Note: When manageMasterUserPassword is enabled, you cannot use other credential properties like password, secret, secretName, excludeCharacters, replicaRegions, or usernameAsString. Only username and encryptionKey are allowed. The secret property exposes a read-only reference to the secret that RDS created, not a CDK-owned secret — addToResourcePolicy() is a no-op, so use secret.grantRead(grantee) to grant access.
Snapshot credentials
As noted above, Databases created with DatabaseInstanceFromSnapshot or ServerlessClusterFromSnapshot will not create user and auto-generated password by default because it's not possible to change the master username for a snapshot. Instead, they will use the existing username and password from the snapshot. You can still generate a new password - to generate a secret similarly to the other constructs, pass in credentials with fromGeneratedSecret() or fromGeneratedPassword().

Connecting
To control who can access the cluster or instance, use the .connections attribute. RDS databases have a default port, so you don't need to specify the port:
ts
declare const cluster: rds.DatabaseCluster;
cluster.connections.allowFromAnyIpv4(ec2.Port.allTraffic(), 'Open to the world');
python
# cluster: rds.DatabaseCluster
cluster.connections.allow_from_any_ipv4(ec2.Port.all_traffic(), "Open to the world")
java
DatabaseCluster cluster;
cluster.connections.allowFromAnyIpv4(Port.allTraffic(), "Open to the world");
csharp
DatabaseCluster cluster;
cluster.Connections.AllowFromAnyIpv4(Port.AllTraffic(), "Open to the world");
go
var cluster DatabaseCluster
cluster.Connections.AllowFromAnyIpv4(ec2.Port_AllTraffic(), jsii.String("Open to the world"))
The endpoints to access your database cluster will be available as the .clusterEndpoint and .readerEndpoint attributes:
ts
declare const cluster: rds.DatabaseCluster;
const writeAddress = cluster.clusterEndpoint.socketAddress; // "HOSTNAME:PORT"
python
# cluster: rds.DatabaseCluster
write_address = cluster.cluster_endpoint.socket_address
java
DatabaseCluster cluster;
String writeAddress = cluster.getClusterEndpoint().getSocketAddress();
csharp
DatabaseCluster cluster;
var writeAddress = cluster.ClusterEndpoint.SocketAddress;
go
var cluster DatabaseCluster
writeAddress := cluster.ClusterEndpoint.socketAddress
For an instance database:
ts
declare const instance: rds.DatabaseInstance;
const address = instance.instanceEndpoint.socketAddress; // "HOSTNAME:PORT"
python
# instance: rds.DatabaseInstance
address = instance.instance_endpoint.socket_address
java
DatabaseInstance instance;
String address = instance.getInstanceEndpoint().getSocketAddress();
csharp
DatabaseInstance instance;
var address = instance.InstanceEndpoint.SocketAddress;
go
var instance DatabaseInstance
address := instance.InstanceEndpoint.socketAddress
Rotating credentials
When the master password is generated and stored in AWS Secrets Manager, it can be rotated automatically:
ts
declare const instance: rds.DatabaseInstance;
declare const mySecurityGroup: ec2.SecurityGroup;
instance.addRotationSingleUser({
automaticallyAfter: Duration.days(7), // defaults to 30 days
excludeCharacters: '!@#$%^&*', // defaults to the set " %+~`#$&*()|[]{}:;<>?!'/@\"\\"
securityGroup: mySecurityGroup, // defaults to an auto-created security group
});
python
# instance: rds.DatabaseInstance
# my_security_group: ec2.SecurityGroup
instance.add_rotation_single_user(
automatically_after=Duration.days(7), # defaults to 30 days
exclude_characters="!@#$%^&*", # defaults to the set " %+~`#/// here*()|[]{}:;<>?!'/@\"\\"
security_group=my_security_group
)
java
DatabaseInstance instance;
SecurityGroup mySecurityGroup;
instance.addRotationSingleUser(RotationSingleUserOptions.builder()
.automaticallyAfter(Duration.days(7)) // defaults to 30 days
.excludeCharacters("!@#$%^&*") // defaults to the set " %+~`#/// here*()|[]{}:;<>?!'/@\"\\"
.securityGroup(mySecurityGroup)
.build());
csharp
DatabaseInstance instance;
SecurityGroup mySecurityGroup;
instance.AddRotationSingleUser(new RotationSingleUserOptions {
AutomaticallyAfter = Duration.Days(7), // defaults to 30 days
ExcludeCharacters = "!@#$%^&*", // defaults to the set " %+~`#/// here*()|[]{}:;<>?!'/@\"\\"
SecurityGroup = mySecurityGroup
});
go
var instance DatabaseInstance
var mySecurityGroup SecurityGroup
instance.addRotationSingleUser(&RotationSingleUserOptions{
AutomaticallyAfter: awscdk.Duration_Days(jsii.Number(7)),
// defaults to 30 days
ExcludeCharacters: jsii.String("!@#$%^&*"),
// defaults to the set " %+~`#/// here*()|[]{}:;<>?!'/@\"\\"
SecurityGroup: mySecurityGroup,
})
For more information on setting up master password rotation for a cluster, see Set up automatic rotation for Amazon RDS secrets.
The multi user rotation scheme is also available:
ts
declare const instance: rds.DatabaseInstance;
declare const myImportedSecret: rds.DatabaseSecret;
instance.addRotationMultiUser('MyUser', {
secret: myImportedSecret, // This secret must have the `masterarn` key
});
python
# instance: rds.DatabaseInstance
# my_imported_secret: rds.DatabaseSecret
instance.add_rotation_multi_user("MyUser",
secret=my_imported_secret
)
java
DatabaseInstance instance;
DatabaseSecret myImportedSecret;
instance.addRotationMultiUser("MyUser", RotationMultiUserOptions.builder()
.secret(myImportedSecret)
.build());
csharp
DatabaseInstance instance;
DatabaseSecret myImportedSecret;
instance.AddRotationMultiUser("MyUser", new RotationMultiUserOptions {
Secret = myImportedSecret
});
go
var instance DatabaseInstance
var myImportedSecret DatabaseSecret
instance.addRotationMultiUser(jsii.String("MyUser"), &RotationMultiUserOptions{
Secret: myImportedSecret,
})
It's also possible to create user credentials together with the instance/cluster and add rotation:
ts
declare const instance: rds.DatabaseInstance;
const myUserSecret = new rds.DatabaseSecret(this, 'MyUserSecret', {
username: 'myuser',
secretName: 'my-user-secret', // optional, defaults to a CloudFormation-generated name
dbname: 'mydb', //optional, defaults to the main database of the RDS cluster this secret gets attached to
masterSecret: instance.secret,
excludeCharacters: '{}[]()\'"/\\', // defaults to the set " %+~`#$&*()|[]{}:;<>?!'/@\"\\"
});
const myUserSecretAttached = myUserSecret.attach(instance); // Adds DB connections information in the secret
instance.addRotationMultiUser('MyUser', { // Add rotation using the multi user scheme
secret: myUserSecretAttached,
});
python
# instance: rds.DatabaseInstance
my_user_secret = rds.DatabaseSecret(self, "MyUserSecret",
username="myuser",
secret_name="my-user-secret", # optional, defaults to a CloudFormation-generated name
dbname="mydb", # optional, defaults to the main database of the RDS cluster this secret gets attached to
master_secret=instance.secret,
exclude_characters="{}[]()'\"/\\"
)
my_user_secret_attached = my_user_secret.attach(instance) # Adds DB connections information in the secret
instance.add_rotation_multi_user("MyUser", # Add rotation using the multi user scheme
secret=my_user_secret_attached)
java
DatabaseInstance instance;
DatabaseSecret myUserSecret = DatabaseSecret.Builder.create(this, "MyUserSecret")
.username("myuser")
.secretName("my-user-secret") // optional, defaults to a CloudFormation-generated name
.dbname("mydb") //optional, defaults to the main database of the RDS cluster this secret gets attached to
.masterSecret(instance.getSecret())
.excludeCharacters("{}[]()'\"/\\")
.build();
ISecret myUserSecretAttached = myUserSecret.attach(instance); // Adds DB connections information in the secret
instance.addRotationMultiUser("MyUser", RotationMultiUserOptions.builder() // Add rotation using the multi user scheme
.secret(myUserSecretAttached).build());
csharp
DatabaseInstance instance;
var myUserSecret = new DatabaseSecret(this, "MyUserSecret", new DatabaseSecretProps {
Username = "myuser",
SecretName = "my-user-secret", // optional, defaults to a CloudFormation-generated name
Dbname = "mydb", //optional, defaults to the main database of the RDS cluster this secret gets attached to
MasterSecret = instance.Secret,
ExcludeCharacters = "{}[]()'\"/\\"
});
var myUserSecretAttached = myUserSecret.Attach(instance); // Adds DB connections information in the secret
instance.AddRotationMultiUser("MyUser", new RotationMultiUserOptions { // Add rotation using the multi user scheme
Secret = myUserSecretAttached });
go
var instance DatabaseInstance
myUserSecret := rds.NewDatabaseSecret(this, jsii.String("MyUserSecret"), &DatabaseSecretProps{
Username: jsii.String("myuser"),
SecretName: jsii.String("my-user-secret"),
// optional, defaults to a CloudFormation-generated name
Dbname: jsii.String("mydb"),
//optional, defaults to the main database of the RDS cluster this secret gets attached to
MasterSecret: instance.Secret,
ExcludeCharacters: jsii.String("{}[]()'\"/\\"),
})
myUserSecretAttached := myUserSecret.attach(instance) // Adds DB connections information in the secret
instance.addRotationMultiUser(jsii.String("MyUser"), &RotationMultiUserOptions{
// Add rotation using the multi user scheme
Secret: myUserSecretAttached,
})
Note: This user must be created manually in the database using the master credentials. The rotation will start as soon as this user exists.
Access to the Secrets Manager API is required for the secret rotation. This can be achieved either with internet connectivity (through NAT) or with a VPC interface endpoint. By default, the rotation Lambda function is deployed in the same subnets as the instance/cluster. If access to the Secrets Manager API is not possible from those subnets or using the default API endpoint, use the vpcSubnets and/or endpoint options:
ts
declare const instance: rds.DatabaseInstance;
declare const myEndpoint: ec2.InterfaceVpcEndpoint;
instance.addRotationSingleUser({
vpcSubnets: { subnetType: ec2.SubnetType.PRIVATE_WITH_EGRESS }, // Place rotation Lambda in private subnets
endpoint: myEndpoint, // Use VPC interface endpoint
});
python
# instance: rds.DatabaseInstance
# my_endpoint: ec2.InterfaceVpcEndpoint
instance.add_rotation_single_user(
vpc_subnets=ec2.SubnetSelection(subnet_type=ec2.SubnetType.PRIVATE_WITH_EGRESS), # Place rotation Lambda in private subnets
endpoint=my_endpoint
)
java
DatabaseInstance instance;
InterfaceVpcEndpoint myEndpoint;
instance.addRotationSingleUser(RotationSingleUserOptions.builder()
.vpcSubnets(SubnetSelection.builder().subnetType(SubnetType.PRIVATE_WITH_EGRESS).build()) // Place rotation Lambda in private subnets
.endpoint(myEndpoint)
.build());
csharp
DatabaseInstance instance;
InterfaceVpcEndpoint myEndpoint;
instance.AddRotationSingleUser(new RotationSingleUserOptions {
VpcSubnets = new SubnetSelection { SubnetType = SubnetType.PRIVATE_WITH_EGRESS }, // Place rotation Lambda in private subnets
Endpoint = myEndpoint
});
go
var instance DatabaseInstance
var myEndpoint InterfaceVpcEndpoint
instance.addRotationSingleUser(&RotationSingleUserOptions{
VpcSubnets: &SubnetSelection{
SubnetType: ec2.SubnetType_PRIVATE_WITH_EGRESS,
},
// Place rotation Lambda in private subnets
Endpoint: myEndpoint,
})
See also aws-cdk-lib/aws-secretsmanager for credentials rotation of existing clusters/instances.
By default, any stack updates will cause AWS Secrets Manager to rotate a secret immediately. To prevent this behavior and wait until the next scheduled rotation window specified via the automaticallyAfter property, set the rotateImmediatelyOnUpdate property to false:
ts
declare const instance: rds.DatabaseInstance;
declare const mySecurityGroup: ec2.SecurityGroup;
instance.addRotationSingleUser({
automaticallyAfter: Duration.days(7), // defaults to 30 days
excludeCharacters: '!@#$%^&*', // defaults to the set " %+~`#$&*()|[]{}:;<>?!'/@\"\\"
securityGroup: mySecurityGroup, // defaults to an auto-created security group
rotateImmediatelyOnUpdate: false, // defaults to true
});
python
# instance: rds.DatabaseInstance
# my_security_group: ec2.SecurityGroup
instance.add_rotation_single_user(
automatically_after=Duration.days(7), # defaults to 30 days
exclude_characters="!@#$%^&*", # defaults to the set " %+~`#/// here*()|[]{}:;<>?!'/@\"\\"
security_group=my_security_group, # defaults to an auto-created security group
rotate_immediately_on_update=False
)
java
DatabaseInstance instance;
SecurityGroup mySecurityGroup;
instance.addRotationSingleUser(RotationSingleUserOptions.builder()
.automaticallyAfter(Duration.days(7)) // defaults to 30 days
.excludeCharacters("!@#$%^&*") // defaults to the set " %+~`#/// here*()|[]{}:;<>?!'/@\"\\"
.securityGroup(mySecurityGroup) // defaults to an auto-created security group
.rotateImmediatelyOnUpdate(false)
.build());
csharp
DatabaseInstance instance;
SecurityGroup mySecurityGroup;
instance.AddRotationSingleUser(new RotationSingleUserOptions {
AutomaticallyAfter = Duration.Days(7), // defaults to 30 days
ExcludeCharacters = "!@#$%^&*", // defaults to the set " %+~`#/// here*()|[]{}:;<>?!'/@\"\\"
SecurityGroup = mySecurityGroup, // defaults to an auto-created security group
RotateImmediatelyOnUpdate = false
});
go
var instance DatabaseInstance
var mySecurityGroup SecurityGroup
instance.addRotationSingleUser(&RotationSingleUserOptions{
AutomaticallyAfter: awscdk.Duration_Days(jsii.Number(7)),
// defaults to 30 days
ExcludeCharacters: jsii.String("!@#$%^&*"),
// defaults to the set " %+~`#/// here*()|[]{}:;<>?!'/@\"\\"
SecurityGroup: mySecurityGroup,
// defaults to an auto-created security group
RotateImmediatelyOnUpdate: jsii.Boolean(false),
})
IAM Authentication
You can also authenticate to a database instance using AWS Identity and Access Management (IAM) database authentication; See <https://docs.aws.amazon.com/AmazonRDS/latest/UserGuide/UsingWithRDS.IAMDBAuth.html> for more information and a list of supported versions and limitations.
The following example shows enabling IAM authentication for a database instance and granting connection access to an IAM role.
Instance
ts
declare const vpc: ec2.Vpc;
const instance = new rds.DatabaseInstance(this, 'Instance', {
engine: rds.DatabaseInstanceEngine.mysql({ version: rds.MysqlEngineVersion.VER_8_0_19 }),
vpc,
iamAuthentication: true, // Optional - will be automatically set if you call grantConnect().
});
const role = new iam.Role(this, 'DBRole', { assumedBy: new iam.AccountPrincipal(this.account) });
instance.grantConnect(role); // Grant the role connection access to the DB.
python
# vpc: ec2.Vpc
instance = rds.DatabaseInstance(self, "Instance",
engine=rds.DatabaseInstanceEngine.mysql(version=rds.MysqlEngineVersion.VER_8_0_19),
vpc=vpc,
iam_authentication=True
)
role = iam.Role(self, "DBRole", assumed_by=iam.AccountPrincipal(self.account))
instance.grant_connect(role)
java
Vpc vpc;
DatabaseInstance instance = DatabaseInstance.Builder.create(this, "Instance")
.engine(DatabaseInstanceEngine.mysql(MySqlInstanceEngineProps.builder().version(MysqlEngineVersion.VER_8_0_19).build()))
.vpc(vpc)
.iamAuthentication(true)
.build();
Role role = Role.Builder.create(this, "DBRole").assumedBy(new AccountPrincipal(this.account)).build();
instance.grantConnect(role);
csharp
Vpc vpc;
var instance = new DatabaseInstance(this, "Instance", new DatabaseInstanceProps {
Engine = DatabaseInstanceEngine.Mysql(new MySqlInstanceEngineProps { Version = MysqlEngineVersion.VER_8_0_19 }),
Vpc = vpc,
IamAuthentication = true
});
var role = new Role(this, "DBRole", new RoleProps { AssumedBy = new AccountPrincipal(Account) });
instance.GrantConnect(role);
go
var vpc Vpc
instance := rds.NewDatabaseInstance(this, jsii.String("Instance"), &DatabaseInstanceProps{
Engine: rds.DatabaseInstanceEngine_Mysql(&MySqlInstanceEngineProps{
Version: rds.MysqlEngineVersion_VER_8_0_19(),
}),
Vpc: Vpc,
IamAuthentication: jsii.Boolean(true),
})
role := iam.NewRole(this, jsii.String("DBRole"), &RoleProps{
AssumedBy: iam.NewAccountPrincipal(this.Account),
})
instance.grantConnect(role)
Proxy
The following example shows granting connection access for RDS Proxy to an IAM role.
ts
declare const vpc: ec2.Vpc;
const cluster = new rds.DatabaseCluster(this, 'Database', {
engine: rds.DatabaseClusterEngine.auroraMysql({
version: rds.AuroraMysqlEngineVersion.VER_3_03_0,
}),
writer: rds.ClusterInstance.provisioned('writer'),
vpc,
});
const proxy = new rds.DatabaseProxy(this, 'Proxy', {
proxyTarget: rds.ProxyTarget.fromCluster(cluster),
secrets: [cluster.secret!],
vpc,
});
const role = new iam.Role(this, 'DBProxyRole', { assumedBy: new iam.AccountPrincipal(this.account) });
proxy.grantConnect(role, 'admin'); // Grant the role connection access to the DB Proxy for database user 'admin'.
python
# vpc: ec2.Vpc
cluster = rds.DatabaseCluster(self, "Database",
engine=rds.DatabaseClusterEngine.aurora_mysql(
version=rds.AuroraMysqlEngineVersion.VER_3_03_0
),
writer=rds.ClusterInstance.provisioned("writer"),
vpc=vpc
)
proxy = rds.DatabaseProxy(self, "Proxy",
proxy_target=rds.ProxyTarget.from_cluster(cluster),
secrets=[cluster.secret],
vpc=vpc
)
role = iam.Role(self, "DBProxyRole", assumed_by=iam.AccountPrincipal(self.account))
proxy.grant_connect(role, "admin")
java
Vpc vpc;
DatabaseCluster cluster = DatabaseCluster.Builder.create(this, "Database")
.engine(DatabaseClusterEngine.auroraMysql(AuroraMysqlClusterEngineProps.builder()
.version(AuroraMysqlEngineVersion.VER_3_03_0)
.build()))
.writer(ClusterInstance.provisioned("writer"))
.vpc(vpc)
.build();
DatabaseProxy proxy = DatabaseProxy.Builder.create(this, "Proxy")
.proxyTarget(ProxyTarget.fromCluster(cluster))
.secrets(List.of(cluster.getSecret()))
.vpc(vpc)
.build();
Role role = Role.Builder.create(this, "DBProxyRole").assumedBy(new AccountPrincipal(this.account)).build();
proxy.grantConnect(role, "admin");
csharp
Vpc vpc;
var cluster = new DatabaseCluster(this, "Database", new DatabaseClusterProps {
Engine = DatabaseClusterEngine.AuroraMysql(new AuroraMysqlClusterEngineProps {
Version = AuroraMysqlEngineVersion.VER_3_03_0
}),
Writer = ClusterInstance.Provisioned("writer"),
Vpc = vpc
});
var proxy = new DatabaseProxy(this, "Proxy", new DatabaseProxyProps {
ProxyTarget = ProxyTarget.FromCluster(cluster),
Secrets = new [] { cluster.Secret },
Vpc = vpc
});
var role = new Role(this, "DBProxyRole", new RoleProps { AssumedBy = new AccountPrincipal(Account) });
proxy.GrantConnect(role, "admin");
go
var vpc Vpc
cluster := rds.NewDatabaseCluster(this, jsii.String("Database"), &DatabaseClusterProps{
Engine: rds.DatabaseClusterEngine_AuroraMysql(&AuroraMysqlClusterEngineProps{
Version: rds.AuroraMysqlEngineVersion_VER_3_03_0(),
}),
Writer: rds.ClusterInstance_Provisioned(jsii.String("writer")),
Vpc: Vpc,
})
proxy := rds.NewDatabaseProxy(this, jsii.String("Proxy"), &DatabaseProxyProps{
ProxyTarget: rds.ProxyTarget_FromCluster(cluster),
Secrets: []ISecret{
cluster.Secret,
},
Vpc: Vpc,
})
role := iam.NewRole(this, jsii.String("DBProxyRole"), &RoleProps{
AssumedBy: iam.NewAccountPrincipal(this.Account),
})
proxy.GrantConnect(role, jsii.String("admin"))
Note: In addition to the setup above, a database user will need to be created to support IAM auth. See <https://docs.aws.amazon.com/AmazonRDS/latest/UserGuide/UsingWithRDS.IAMDBAuth.DBAccounts.html> for setup instructions.
To specify the details of authentication used by a proxy to log in as a specific database user use the clientPasswordAuthType property:
ts
declare const vpc: ec2.Vpc;
const cluster = new rds.DatabaseCluster(this, 'Database', {
engine: rds.DatabaseClusterEngine.auroraMysql({
version: rds.AuroraMysqlEngineVersion.VER_3_03_0,
}),
writer: rds.ClusterInstance.provisioned('writer'),
vpc,
});
const proxy = new rds.DatabaseProxy(this, 'Proxy', {
proxyTarget: rds.ProxyTarget.fromCluster(cluster),
secrets: [cluster.secret!],
vpc,
clientPasswordAuthType: rds.ClientPasswordAuthType.MYSQL_NATIVE_PASSWORD,
});
python
# vpc: ec2.Vpc
cluster = rds.DatabaseCluster(self, "Database",
engine=rds.DatabaseClusterEngine.aurora_mysql(
version=rds.AuroraMysqlEngineVersion.VER_3_03_0
),

vpc=vpc
)
proxy = rds.DatabaseProxy(self, "Proxy",
proxy_target=rds.ProxyTarget.from_cluster(cluster),
secrets=[cluster.secret],
vpc=vpc,
client_password_auth_type=rds.ClientPasswordAuthType.MYSQL_NATIVE_PASSWORD
)
java
Vpc vpc;

Default Authentication Scheme
RDS Proxy supports different authentication schemes to connect to your database. You can configure the default authentication scheme using the defaultAuthScheme property.
When using DefaultAuthScheme.IAM_AUTH, the proxy uses end-to-end IAM authentication to connect to the database, eliminating the need for secrets stored in AWS Secrets Manager:
ts
declare const vpc: ec2.Vpc;
const instance = new rds.DatabaseInstance(this, 'Database', {
engine: rds.DatabaseInstanceEngine.postgres({
version: rds.PostgresEngineVersion.VER_17_7,
}),
vpc,
iamAuthentication: true,
});
const proxy = new rds.DatabaseProxy(this, 'Proxy', {
proxyTarget: rds.ProxyTarget.fromInstance(instance),
vpc,
defaultAuthScheme: rds.DefaultAuthScheme.IAM_AUTH, // No secrets required
});
// Grant IAM permissions for database connection
const role = new iam.Role(this, 'DBRole', { assumedBy: new iam.AccountPrincipal(this.account) });
proxy.grantConnect(role, 'database-user'); // Database user must be specified when using IAM auth
python
# vpc: ec2.Vpc
instance = rds.DatabaseInstance(self, "Database",
engine=rds.DatabaseInstanceEngine.postgres(
version=rds.PostgresEngineVersion.VER_17_7

# Grant IAM permissions for database connection
role = iam.Role(self, "DBRole", assumed_by=iam.AccountPrincipal(self.account))
proxy.grant_connect(role, "database-user")
java
Vpc vpc;

});
var role = new Role(this, "AppRole", new RoleProps { AssumedBy = new ServicePrincipal("someservice.amazonaws.com") });
cluster.GrantConnect(role, "somedbuser");
go
var vpc Vpc

AssumedBy: iam.NewServicePrincipal(jsii.String("someservice.amazonaws.com")),
})
cluster.GrantConnect(role, jsii.String("somedbuser"))
Note: In addition to the setup above, a database user will need to be created to support IAM auth. See <https://docs.aws.amazon.com/AmazonRDS/latest/UserGuide/UsingWithRDS.IAMDBAuth.DBAccounts.html> for setup instructions.
Kerberos Authentication
You can also authenticate using Kerberos to a database instance using AWS Managed Microsoft AD for authentication; See <https://docs.aws.amazon.com/AmazonRDS/latest/UserGuide/kerberos-authentication.html> for more information and a list of supported versions and limitations.
The following example shows enabling domain support for a database instance and creating an IAM role to access Directory Services.
ts

Note: In addition to the setup above, you need to make sure that the database instance or cluster has network connectivity to the domain controllers. This includes enabling cross-VPC traffic if in a different VPC and setting up the appropriate security groups/network ACL to allow traffic between the database instance and domain controllers. Once configured, see <https://docs.aws.amazon.com/AmazonRDS/latest/UserGuide/kerberos-authentication.html> for details on configuring users for each available database engine.
Metrics
Database instances and clusters both expose metrics (cloudwatch.Metric):
ts
// The number of database connections in use (average over 5 minutes)
declare const instance: rds.DatabaseInstance;
const dbConnections = instance.metricDatabaseConnections();
// Average CPU utilization over 5 minutes
declare const cluster: rds.DatabaseCluster;
const cpuUtilization = cluster.metricCPUUtilization();
// The average amount of time taken per disk I/O operation (average over 1 minute)
const readLatency = instance.metric('ReadLatency', { statistic: 'Average', period: Duration.seconds(60) });
python
# The number of database connections in use (average over 5 minutes)
# instance: rds.DatabaseInstance
# Average CPU utilization over 5 minutes
# cluster: rds.DatabaseCluster
db_connections = instance.metric_database_connections()
cpu_utilization = cluster.metric_cpu_utilization()
# The average amount of time taken per disk I/O operation (average over 1 minute)
read_latency = instance.metric("ReadLatency", statistic="Average", period=Duration.seconds(60))
java
// The number of database connections in use (average over 5 minutes)
DatabaseInstance instance;
// Average CPU utilization over 5 minutes
DatabaseCluster cluster;
Metric dbConnections = instance.metricDatabaseConnections();

var readLatency = instance.Metric("ReadLatency", new MetricOptions { Statistic = "Average", Period = Duration.Seconds(60) });
go
// The number of database connections in use (average over 5 minutes)
var instance DatabaseInstance
// Average CPU utilization over 5 minutes
var cluster DatabaseCluster
dbConnections := instance.metricDatabaseConnections()

// The average amount of time taken per disk I/O operation (average over 1 minute)
readLatency := instance.metric(jsii.String("ReadLatency"), &MetricOptions{
Statistic: jsii.String("Average"),
Period: awscdk.Duration_Seconds(jsii.Number(60)),
})
Enabling S3 integration
Data in S3 buckets can be imported to and exported from certain database engines using SQL queries. To enable this functionality, set the s3ImportBuckets and s3ExportBuckets properties for import and export respectively. When configured, the CDK automatically creates and configures IAM roles as required. Additionally, the s3ImportRole and s3ExportRole properties can be used to set this role directly. Note: To use s3ImportRole and s3ExportRole with Aurora PostgreSQL, you must also enable the S3 import and export features when you create the DatabaseClusterEngine.
You can read more about loading data to (or from) S3 here:
- Aurora MySQL - import and export.
- Aurora PostgreSQL - import and export.
- Microsoft SQL Server - import and export
- PostgreSQL - import and export
- Oracle - import and export
The following snippet sets up a database cluster with different S3 buckets where the data is imported and exported -
ts
import * as s3 from 'aws-cdk-lib/aws-s3';
declare const vpc: ec2.Vpc;
const importBucket = new s3.Bucket(this, 'importbucket');
const exportBucket = new s3.Bucket(this, 'exportbucket');

Creating a Database Proxy
Amazon RDS Proxy sits between your application and your relational database to efficiently manage connections to the database and improve scalability of the application. Learn more about at Amazon RDS Proxy.
RDS Proxy is supported for MySQL, MariaDB, Postgres, and SQL Server.
The following code configures an RDS Proxy for a DatabaseInstance.
ts
declare const vpc: ec2.Vpc;
declare const securityGroup: ec2.SecurityGroup;
declare const secrets: secretsmanager.Secret[];
declare const dbInstance: rds.DatabaseInstance;
const proxy = dbInstance.addProxy('proxy', {
borrowTimeout: Duration.seconds(30),
maxConnectionsPercent: 50,
secrets,
vpc,
});
python
# vpc: ec2.Vpc
# security_group: ec2.SecurityGroup
# secrets: List[secretsmanager.Secret[]]
# db_instance: rds.DatabaseInstance
proxy = db_instance.add_proxy("proxy",
borrow_timeout=Duration.seconds(30),
max_connections_percent=50,
secrets=secrets,
vpc=vpc
)
java
Vpc vpc;
SecurityGroup securityGroup;
Secret[] secrets;
DatabaseInstance dbInstance;
DatabaseProxy proxy = dbInstance.addProxy("proxy", DatabaseProxyOptions.builder()
.borrowTimeout(Duration.seconds(30))
.maxConnectionsPercent(50)
.secrets(secrets)
.vpc(vpc)
.build());
csharp
Vpc vpc;
SecurityGroup securityGroup;
Secret[] secrets;
DatabaseInstance dbInstance;
var proxy = dbInstance.AddProxy("proxy", new DatabaseProxyOptions {
BorrowTimeout = Duration.Seconds(30),
MaxConnectionsPercent = 50,
Secrets = secrets,
Vpc = vpc
});
go
var vpc Vpc
var securityGroup SecurityGroup
var secrets []Secret
var dbInstance DatabaseInstance
proxy := dbInstance.AddProxy(jsii.String("proxy"), &DatabaseProxyOptions{
BorrowTimeout: awscdk.Duration_Seconds(jsii.Number(30)),
MaxConnectionsPercent: jsii.Number(50),
Secrets: Secrets,
Vpc: Vpc,
})
Proxy Endpoint
The following example add additional endpoint to RDS Proxy.
ts
declare const vpc: ec2.Vpc;
declare const secrets: secretsmanager.Secret[];
declare const dbInstance: rds.DatabaseInstance;
const proxy = dbInstance.addProxy('Proxy', {
secrets,
vpc,
});
// Add a reader endpoint
proxy.addEndpoint('ProxyEndpoint', {
vpc,
targetRole: rds.ProxyEndpointTargetRole.READ_ONLY,
});
python
# vpc: ec2.Vpc
# secrets: List[secretsmanager.Secret[]]
# db_instance: rds.DatabaseInstance
proxy = db_instance.add_proxy("Proxy",
secrets=secrets,
vpc=vpc
)
# Add a reader endpoint
proxy.add_endpoint("ProxyEndpoint",
vpc=vpc,
target_role=rds.ProxyEndpointTargetRole.READ_ONLY
)
java
Vpc vpc;
Secret[] secrets;
DatabaseInstance dbInstance;
DatabaseProxy proxy = dbInstance.addProxy("Proxy", DatabaseProxyOptions.builder()
.secrets(secrets)
.vpc(vpc)
.build());
// Add a reader endpoint
proxy.addEndpoint("ProxyEndpoint", DatabaseProxyEndpointOptions.builder()

csharp
Vpc vpc;
Secret[] secrets;
DatabaseInstance dbInstance;
var proxy = dbInstance.AddProxy("Proxy", new DatabaseProxyOptions {
Secrets = secrets,
Vpc = vpc
});
// Add a reader endpoint
proxy.AddEndpoint("ProxyEndpoint", new DatabaseProxyEndpointOptions {
Vpc = vpc,
TargetRole = ProxyEndpointTargetRole.READ_ONLY
});
go
var vpc Vpc
var secrets []Secret
var dbInstance DatabaseInstance
proxy := dbInstance.AddProxy(jsii.String("Proxy"), &DatabaseProxyOptions{
Secrets: Secrets,
Vpc: Vpc,
})
// Add a reader endpoint
proxy.AddEndpoint(jsii.String("ProxyEndpoint"), &DatabaseProxyEndpointOptions{
Vpc: Vpc,
TargetRole: rds.ProxyEndpointTargetRole_READ_ONLY,
})
Exporting Logs
You can publish database logs to Amazon CloudWatch Logs. With CloudWatch Logs, you can perform real-time analysis of the log data, store the data in highly durable storage, and manage the data with the CloudWatch Logs Agent. This is available for both database instances and clusters; the types of logs available depend on the database type and engine being used.
ts
import * as logs from 'aws-cdk-lib/aws-logs';
declare const myLogsPublishingRole: iam.Role;

Option Groups
Some DB engines offer additional features that make it easier to manage data and databases, and to provide additional security for your database. Amazon RDS uses option groups to enable and configure these features. An option group can specify features, called options, that are available for a particular Amazon RDS DB instance.
ts
declare const vpc: ec2.Vpc;
declare const securityGroup: ec2.SecurityGroup;
new rds.OptionGroup(this, 'Options', {
engine: rds.DatabaseInstanceEngine.oracleSe2({
version: rds.OracleEngineVersion.VER_19,
}),
configurations: [
{
name: 'OEM',
port: 5500,
vpc,
securityGroups: [securityGroup], // Optional - a default group will be created if not provided.
},
],
optionGroupName: 'MyOptionGroup'
});
python
# vpc: ec2.Vpc
# security_group: ec2.SecurityGroup
rds.OptionGroup(self, "Options",
engine=rds.DatabaseInstanceEngine.oracle_se2(
version=rds.OracleEngineVersion.VER_19
),

Parameter Groups
Database parameters specify how the database is configured. For example, database parameters can specify the amount of resources, such as memory, to allocate to a database. You manage your database configuration by associating your DB instances with parameter groups. Amazon RDS defines parameter groups with default settings.
You can create your own parameter group for your cluster or instance and associate it with your database:
ts
declare const vpc: ec2.Vpc;
const parameterGroup = new rds.ParameterGroup(this, 'ParameterGroup', {
engine: rds.DatabaseInstanceEngine.sqlServerEe({
version: rds.SqlServerEngineVersion.VER_11,
}),
name: 'my-parameter-group',
parameters: {
locks: '100',
},
});
new rds.DatabaseInstance(this, 'Database', {
engine: rds.DatabaseInstanceEngine.SQL_SERVER_EE,
vpc,
parameterGroup,
});
python
# vpc: ec2.Vpc
parameter_group = rds.ParameterGroup(self, "ParameterGroup",
engine=rds.DatabaseInstanceEngine.sql_server_ee(
version=rds.SqlServerEngineVersion.VER_11
),
name="my-parameter-group",
parameters={
"locks": "100"
}
)
rds.DatabaseInstance(self, "Database",
engine=rds.DatabaseInstanceEngine.SQL_SERVER_EE,
vpc=vpc,
parameter_group=parameter_group
)
java
Vpc vpc;
ParameterGroup parameterGroup = ParameterGroup.Builder.create(this, "ParameterGroup")
.engine(DatabaseInstanceEngine.sqlServerEe(SqlServerEeInstanceEngineProps.builder()
.version(SqlServerEngineVersion.VER_11)
.build()))
.name("my-parameter-group")
.parameters(Map.of(
"locks", "100"))
.build();
DatabaseInstance.Builder.create(this, "Database")
.engine(DatabaseInstanceEngine.SQL_SERVER_EE)
.vpc(vpc)
.parameterGroup(parameterGroup)
.build();
csharp
Vpc vpc;
var parameterGroup = new ParameterGroup(this, "ParameterGroup", new ParameterGroupProps {
Engine = DatabaseInstanceEngine.SqlServerEe(new SqlServerEeInstanceEngineProps {
Version = SqlServerEngineVersion.VER_11
}),
Name = "my-parameter-group",
Parameters = new Dictionary<string, string> {
{ "locks", "100" }
}
});
new DatabaseInstance(this, "Database", new DatabaseInstanceProps {
Engine = DatabaseInstanceEngine.SQL_SERVER_EE,
Vpc = vpc,
ParameterGroup = parameterGroup
});
go
var vpc Vpc
parameterGroup := rds.NewParameterGroup(this, jsii.String("ParameterGroup"), &ParameterGroupProps{
Engine: rds.DatabaseInstanceEngine_SqlServerEe(&SqlServerEeInstanceEngineProps{
Version: rds.SqlServerEngineVersion_VER_11(),
}),
Name: jsii.String("my-parameter-group"),
Parameters: map[string]*string{
"locks": jsii.String("100"),
},
})
rds.NewDatabaseInstance(this, jsii.String("Database"), &DatabaseInstanceProps{
Engine: rds.DatabaseInstanceEngine_SQL_SERVER_EE(),
Vpc: Vpc,
ParameterGroup: ParameterGroup,
})
Another way to specify parameters is to use the inline field parameters that creates an RDS parameter group for you. You can use this if you do not want to reuse the parameter group instance for different instances:
ts
declare const vpc: ec2.Vpc;
new rds.DatabaseInstance(this, 'Database', {
engine: rds.DatabaseInstanceEngine.sqlServerEe({ version: rds.SqlServerEngineVersion.VER_11 }),
vpc,
parameters: {
locks: '100',
},
});
python
# vpc: ec2.Vpc
rds.DatabaseInstance(self, "Database",
engine=rds.DatabaseInstanceEngine.sql_server_ee(version=rds.SqlServerEngineVersion.VER_11),
vpc=vpc,
parameters={
"locks": "100"
}
)
java
Vpc vpc;
DatabaseInstance.Builder.create(this, "Database")
.engine(DatabaseInstanceEngine.sqlServerEe(SqlServerEeInstanceEngineProps.builder().version(SqlServerEngineVersion.VER_11).build()))
.vpc(vpc)
.parameters(Map.of(
"locks", "100"))
.build();
csharp
Vpc vpc;
new DatabaseInstance(this, "Database", new DatabaseInstanceProps {
Engine = DatabaseInstanceEngine.SqlServerEe(new SqlServerEeInstanceEngineProps { Version = SqlServerEngineVersion.VER_11 }),
Vpc = vpc,
Parameters = new Dictionary<string, string> {
{ "locks", "100" }
}
});
go
var vpc Vpc
rds.NewDatabaseInstance(this, jsii.String("Database"), &DatabaseInstanceProps{
Engine: rds.DatabaseInstanceEngine_SqlServerEe(&SqlServerEeInstanceEngineProps{
Version: rds.SqlServerEngineVersion_VER_11(),
}),
Vpc: Vpc,
Parameters: map[string]*string{
"locks": jsii.String("100"),
},
})
You cannot specify a parameter map and a parameter group at the same time.
Creating Standalone Parameter Groups
In some scenarios, you may want to create a parameter group that exists independently of a database instance or cluster.
By default, ParameterGroup uses a lazy creation pattern and only generates the CloudFormation resource when bound to an instance or cluster. To create a standalone parameter group, use the static factory methods forInstance() or forCluster():
For instance parameter group (AWS::RDS::DBParameterGroup):
ts
const parameterGroup = rds.ParameterGroup.forInstance(this, 'InstanceParameterGroup', {
engine: rds.DatabaseInstanceEngine.mysql({
version: rds.MysqlEngineVersion.VER_8_0_35,
}),
description: 'Parameter group for MySQL',
parameters: {
max_connections: '150',
slow_query_log: '1',
},
});
python
parameter_group = rds.ParameterGroup.for_instance(self, "InstanceParameterGroup",
engine=rds.DatabaseInstanceEngine.mysql(
version=rds.MysqlEngineVersion.VER_8_0_35
),
description="Parameter group for MySQL",
parameters={
"max_connections": "150",
"slow_query_log": "1"
}
)
java
IParameterGroup parameterGroup = ParameterGroup.forInstance(this, "InstanceParameterGroup", ParameterGroupProps.builder()
.engine(DatabaseInstanceEngine.mysql(MySqlInstanceEngineProps.builder()
.version(MysqlEngineVersion.VER_8_0_35)
.build()))
.description("Parameter group for MySQL")
.parameters(Map.of(
"max_connections", "150",
"slow_query_log", "1"))
.build());
csharp
var parameterGroup = ParameterGroup.ForInstance(this, "InstanceParameterGroup", new ParameterGroupProps {
Engine = DatabaseInstanceEngine.Mysql(new MySqlInstanceEngineProps {
Version = MysqlEngineVersion.VER_8_0_35
}),
Description = "Parameter group for MySQL",
Parameters = new Dictionary<string, string> {
{ "max_connections", "150" },
{ "slow_query_log", "1" }
}
});
go
parameterGroup := rds.ParameterGroup_ForInstance(this, jsii.String("InstanceParameterGroup"), &ParameterGroupProps{
Engine: rds.DatabaseInstanceEngine_Mysql(&MySqlInstanceEngineProps{
Version: rds.MysqlEngineVersion_VER_8_0_35(),
}),
Description: jsii.String("Parameter group for MySQL"),
Parameters: map[string]*string{
"max_connections": jsii.String("150"),
"slow_query_log": jsii.String("1"),
},
})
For cluster parameter group (AWS::RDS::DBClusterParameterGroup):
ts
const clusterParameterGroup = rds.ParameterGroup.forCluster(this, 'ClusterParameterGroup', {
engine: rds.DatabaseClusterEngine.auroraMysql({
version: rds.AuroraMysqlEngineVersion.VER_3_04_0,
}),

Serverless v1
Amazon Aurora Serverless v1 is an on-demand, auto-scaling configuration for Amazon Aurora. The database will automatically start up, shut down, and scale capacity up or down based on your application's needs. It enables you to run your database in the cloud without managing any database instances.
The following example initializes an Aurora Serverless v1 PostgreSql cluster. Aurora Serverless clusters can specify scaling properties which will be used to automatically scale the database cluster seamlessly based on the workload.
ts
declare const vpc: ec2.Vpc;
const cluster = new rds.ServerlessCluster(this, 'AnotherCluster', {

parameterGroup: rds.ParameterGroup.fromParameterGroupName(this, 'ParameterGroup', 'default.aurora-postgresql11'),
vpc,
scaling: {
autoPause: Duration.minutes(10), // default is to pause after 5 minutes of idle time
minCapacity: rds.AuroraCapacityUnit.ACU_8, // default is 2 Aurora capacity units (ACUs)
maxCapacity: rds.AuroraCapacityUnit.ACU_32, // default is 16 Aurora capacity units (ACUs)
timeout: Duration.seconds(100), // default is 5 minutes
timeoutAction: rds.TimeoutAction.FORCE_APPLY_CAPACITY_CHANGE // default is ROLLBACK_CAPACITY_CHANGE

})
Note: The rds.ServerlessCluster class is for Aurora Serverless v1. If you want to use Aurora Serverless v2, use the rds.DatabaseCluster class.
Aurora Serverless v1 Clusters do not support the following features:
- Loading data from an Amazon S3 bucket
- Saving data to an Amazon S3 bucket
- Invoking an AWS Lambda function with an Aurora MySQL native function
- Aurora replicas
- Backtracking
- Multi-master clusters
- Database cloning
- IAM database cloning
- IAM database authentication
- Restoring a snapshot from MySQL DB instance
- Performance Insights
- RDS Proxy

Use ServerlessClusterFromSnapshot to create a serverless cluster from a snapshot:
ts
declare const vpc: ec2.Vpc;
new rds.ServerlessClusterFromSnapshot(this, 'Cluster', {
engine: rds.DatabaseClusterEngine.AURORA_MYSQL,
vpc,
snapshotIdentifier: 'mySnapshot',
});
python
# vpc: ec2.Vpc

vpc=vpc,
snapshot_identifier="mySnapshot"
)
java
Vpc vpc;
ServerlessClusterFromSnapshot.Builder.create(this, "Cluster")
.engine(DatabaseClusterEngine.AURORA_MYSQL)
.vpc(vpc)
.snapshotIdentifier("mySnapshot")
.build();
csharp
Vpc vpc;
new ServerlessClusterFromSnapshot(this, "Cluster", new ServerlessClusterFromSnapshotProps {
Engine = DatabaseClusterEngine.AURORA_MYSQL,
Vpc = vpc,
SnapshotIdentifier = "mySnapshot"
});
go

})
Data API
You can access your Aurora DB cluster using the built-in Data API. The Data API doesn't require a persistent connection to the DB cluster. Instead, it provides a secure HTTP endpoint and integration with AWS SDKs.
The following example shows granting Data API access to a Lambda function.
ts
declare const vpc: ec2.Vpc;
declare const fn: lambda.Function;
declare const secret: secretsmanager.Secret;
// Create a serverless V1 cluster
const serverlessV1Cluster = new rds.ServerlessCluster(this, 'AnotherCluster', {
engine: rds.DatabaseClusterEngine.AURORA_MYSQL,
vpc, // this parameter is optional for serverless Clusters
enableDataApi: true, // Optional - will be automatically set if you call grantDataApiAccess()
});
serverlessV1Cluster.grantDataApiAccess(fn);
// Create an Aurora cluster
const cluster = new rds.DatabaseCluster(this, 'Cluster', {
engine: rds.DatabaseClusterEngine.AURORA_MYSQL,
vpc,
enableDataApi: true, // Optional - will be automatically set if you call grantDataApiAccess()
});
cluster.grantDataApiAccess(fn);
// Import an Aurora cluster
const importedCluster = rds.DatabaseCluster.fromDatabaseClusterAttributes(this, 'ImportedCluster', {
clusterIdentifier: 'clusterIdentifier',
secret,
dataApiEnabled: true,
});
importedCluster.grantDataApiAccess(fn);
python
# vpc: ec2.Vpc
# fn: lambda.Function
# secret: secretsmanager.Secret
# Create a serverless V1 cluster
serverless_v1_cluster = rds.ServerlessCluster(self, "AnotherCluster",
engine=rds.DatabaseClusterEngine.AURORA_MYSQL,
vpc=vpc, # this parameter is optional for serverless Clusters
enable_data_api=True
)
serverless_v1_cluster.grant_data_api_access(fn)
# Create an Aurora cluster
cluster = rds.DatabaseCluster(self, "Cluster",
engine=rds.DatabaseClusterEngine.AURORA_MYSQL,
vpc=vpc,
enable_data_api=True
)

Note: To invoke the Data API, the resource will need to read the secret associated with the cluster.
To learn more about using the Data API, see the documentation.
Default VPC
The vpc parameter is optional.
If not provided, the cluster will be created in the default VPC of the account and region. As this VPC is not deployed with AWS CDK, you can't configure the vpcSubnets, subnetGroup or securityGroups of the Aurora Serverless Cluster. If you want to provide one of vpcSubnets, subnetGroup or securityGroups parameter, please provide a vpc.
Preferred Maintenance Window
When creating an RDS cluster, it is possible to (optionally) specify a preferred maintenance window for the cluster as well as the instances under the cluster. See AWS docs for more information regarding maintenance windows.
The following code snippet shows an example of setting the cluster's maintenance window to 22:15-22:45 (UTC) on Saturdays, but setting the instances' maintenance window to 23:15-23:45 on Sundays
ts
declare const vpc: ec2.Vpc;
new rds.DatabaseCluster(this, 'DatabaseCluster', {
engine: rds.DatabaseClusterEngine.AURORA,
instanceProps: {
vpc: vpc,
preferredMaintenanceWindow: 'Sun:23:15-Sun:23:45',

preferredMaintenanceWindow: 'Sat:22:15-Sat:22:45',
});
python

PreferredMaintenanceWindow: jsii.String("Sat:22:15-Sat:22:45"),
})
Performance Insights
You can enable Performance Insights for a clustered database or an instance database.
Clustered Database
You can enable Performance Insights at cluster level or instance level.
To enable Performance Insights at the cluster level, set the enablePerformanceInsights property for the DatabaseCluster to true. If you want to specify the detailed settings, you can use the performanceInsightRetention and performanceInsightEncryptionKey properties.
The settings are then applied to all instances in the cluster.

})
To enable Performance Insights at the instance level, set the same properties for each instance of the writer and the readers.
In this way, different settings can be applied to different instances in a cluster.
Note: If Performance Insights is enabled at the cluster level, it is also automatically enabled for each instance. If specified, Performance Insights for each instance require the same retention period and encryption key as the cluster level.

Enhanced Monitoring
With Enhanced Monitoring, you can monitor the operating system of your DB instance in real time.
To enable Enhanced Monitoring for a clustered database, set the monitoringInterval property. This value is applied at instance level to all instances in the cluster by default.
If you want to enable enhanced monitoring at the cluster level, you can set the enableClusterLevelEnhancedMonitoring property to true. Note that you must set monitoringInterval when using enableClusterLevelEnhancedMonitoring

Here's how DatabaseInstance.fromLookup() can be used:
ts
declare const myUserRole: iam.Role;
const dbFromLookup = rds.DatabaseInstance.fromLookup(this, 'dbFromLookup', {
instanceIdentifier: 'instanceId',
});
// Grant a connection
dbFromLookup.grantConnect(myUserRole, 'my-user-id');
python
# my_user_role: iam.Role
db_from_lookup = rds.DatabaseInstance.from_lookup(self, "dbFromLookup",
instance_identifier="instanceId"
)
# Grant a connection
db_from_lookup.grant_connect(my_user_role, "my-user-id")
java
Role myUserRole;
IDatabaseInstance dbFromLookup = DatabaseInstance.fromLookup(this, "dbFromLookup", DatabaseInstanceLookupOptions.builder()
.instanceIdentifier("instanceId")
.build());
// Grant a connection
dbFromLookup.grantConnect(myUserRole, "my-user-id");
csharp
Role myUserRole;
var dbFromLookup = DatabaseInstance.FromLookup(this, "dbFromLookup", new DatabaseInstanceLookupOptions {
InstanceIdentifier = "instanceId"
});
// Grant a connection
dbFromLookup.GrantConnect(myUserRole, "my-user-id");
go
