The AWS::RDS::DBParameterGroup
resource creates a custom parameter group for an RDS database family.
This type can be declared in a template and referenced in the DBParameterGroupName
property of an [AWS::RDS::DBInstance](https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/aws-properties-rds-database-instance.html)
resource.
For information about configuring parameters for Amazon RDS DB instances, see Working with parameter groups in the Amazon RDS User Guide .
For information about configuring parameters for Amazon Aurora DB instances, see Working with parameter groups in the Amazon Aurora User Guide .
Applying a parameter group to a DB instance may require the DB instance to reboot, resulting in a database outage for the duration of the reboot.

description
Type:
string
Provides the customer-specified description for this DB parameter group.
family
Type:
string
The DB parameter group family name.
A DB parameter group can be associated with one and only one DB parameter group family, and can be applied only to a DB instance running a database engine and engine version compatible with that DB parameter group family.
To list all of the available parameter group families for a DB engine, use the following command:
aws rds describe-db-engine-versions --query "DBEngineVersions[].DBParameterGroupFamily" --engine <engine>
For example, to list all of the available parameter group families for the MySQL DB engine, use the following command:
aws rds describe-db-engine-versions --query "DBEngineVersions[].DBParameterGroupFamily" --engine mysql
The output contains duplicates.
The following are the valid DB engine values:
aurora-mysql
aurora-postgresql
db2-ae
db2-se
mysql
oracle-ee
oracle-ee-cdb
oracle-se2
oracle-se2-cdb
postgres
sqlserver-ee
sqlserver-se
sqlserver-ex
sqlserver-web
dbParameterGroupName?
Type:
string
(optional)
The name of the DB parameter group.
Constraints:
- Must be 1 to 255 letters, numbers, or hyphens.
- First character must be a letter
- Can't end with a hyphen or contain two consecutive hyphens
If you don't specify a value for DBParameterGroupName
property, a name is automatically created for the DB parameter group.
This value is stored as a lowercase string.
parameters?
Type:
any
(optional)
An array of parameter names and values for the parameter update.
You must specify at least one parameter name and value.
For more information about parameter groups, see Working with parameter groups in the Amazon RDS User Guide , or Working with parameter groups in the Amazon Aurora User Guide .
AWS CloudFormation doesn't support specifying an apply method for each individual parameter. The default apply method for each parameter is used.

addDeletionOverride(path)
public addDeletionOverride(path: string): void
Parameters
- path
string
— The path of the value to delete.
Syntactic sugar for addOverride(path, undefined)
.
addDependency(target)
public addDependency(target: CfnResource): void
Parameters
- target
Cfn
Resource
Indicates that this resource depends on another resource and cannot be provisioned unless the other resource has been successfully provisioned.
This can be used for resources across stacks (or nested stack) boundaries and the dependency will automatically be transferred to the relevant scope.
addDependsOn(target)
public addDependsOn(target: CfnResource): void
⚠️ Deprecated: use addDependency
Parameters
- target
Cfn
Resource
Indicates that this resource depends on another resource and cannot be provisioned unless the other resource has been successfully provisioned.
addMetadata(key, value)
public addMetadata(key: string, value: any): void
Parameters
- key
string
- value
any
Add a value to the CloudFormation Resource Metadata.
Note that this is a different set of metadata from CDK node metadata; this metadata ends up in the stack template under the resource, whereas CDK node metadata ends up in the Cloud Assembly.](https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/metadata-section-structure.html
Note that this is a different set of metadata from CDK node metadata; this metadata ends up in the stack template under the resource, whereas CDK node metadata ends up in the Cloud Assembly.)
addOverride(path, value)
public addOverride(path: string, value: any): void
Parameters
- path
string
— - The path of the property, you can use dot notation to override values in complex types. - value
any
— - The value.
Adds an override to the synthesized CloudFormation resource.
To add a
property override, either use addPropertyOverride
or prefix path
with
"Properties." (i.e. Properties.TopicName
).
If the override is nested, separate each nested level using a dot (.) in the path parameter. If there is an array as part of the nesting, specify the index in the path.
To include a literal .
in the property name, prefix with a \
. In most
programming languages you will need to write this as "\\."
because the
\
itself will need to be escaped.
For example,
cfnResource.addOverride('Properties.GlobalSecondaryIndexes.0.Projection.NonKeyAttributes', ['myattribute']);
cfnResource.addOverride('Properties.GlobalSecondaryIndexes.1.ProjectionType', 'INCLUDE');
would add the overrides
"Properties": {
"GlobalSecondaryIndexes": [
{
"Projection": {
"NonKeyAttributes": [ "myattribute" ]
...
}
...
},
{
"ProjectionType": "INCLUDE"
...
},
]
...
}
The value
argument to addOverride
will not be processed or translated
in any way. Pass raw JSON values in here with the correct capitalization
for CloudFormation. If you pass CDK classes or structs, they will be
rendered with lowercased key names, and CloudFormation will reject the
template.
addPropertyDeletionOverride(propertyPath)
public addPropertyDeletionOverride(propertyPath: string): void
Parameters
- propertyPath
string
— The path to the property.
Adds an override that deletes the value of a property from the resource definition.
addPropertyOverride(propertyPath, value)
public addPropertyOverride(propertyPath: string, value: any): void
Parameters
- propertyPath
string
— The path of the property. - value
any
— The value.
Adds an override to a resource property.
Syntactic sugar for addOverride("Properties.<...>", value)
.
applyRemovalPolicy(policy?, options?)
public applyRemovalPolicy(policy?: RemovalPolicy, options?: RemovalPolicyOptions): void
Parameters
- policy
Removal
Policy - options
Removal
Policy Options
Sets the deletion policy of the resource based on the removal policy specified.
The Removal Policy controls what happens to this resource when it stops being managed by CloudFormation, either because you've removed it from the CDK application or because you've made a change that requires the resource to be replaced.
The resource can be deleted (RemovalPolicy.DESTROY
), or left in your AWS
account for data recovery and cleanup later (RemovalPolicy.RETAIN
). In some
cases, a snapshot can be taken of the resource prior to deletion
(RemovalPolicy.SNAPSHOT
). A list of resources that support this policy
can be found in the following link:
getAtt(attributeName, typeHint?)
public getAtt(attributeName: string, typeHint?: ResolutionTypeHint): Reference
Parameters
- attributeName
string
— The name of the attribute. - typeHint
Resolution
Type Hint
Returns
Returns a token for an runtime attribute of this resource.
Ideally, use generated attribute accessors (e.g. resource.arn
), but this can be used for future compatibility
in case there is no generated attribute.
getMetadata(key)
public getMetadata(key: string): any
Parameters
- key
string
Returns
any
Retrieve a value value from the CloudFormation Resource Metadata.
Note that this is a different set of metadata from CDK node metadata; this metadata ends up in the stack template under the resource, whereas CDK node metadata ends up in the Cloud Assembly.](https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/metadata-section-structure.html
Note that this is a different set of metadata from CDK node metadata; this metadata ends up in the stack template under the resource, whereas CDK node metadata ends up in the Cloud Assembly.)
inspect(inspector)

Parameters
- inspector
Tree
— tree inspector to collect and process attributes.Inspector
Examines the CloudFormation resource and discloses attributes.
obtainDependencies()
public obtainDependencies(): Stack | CfnResource[]
