class aws_cdk.aws_neptune.CfnDBInstance(scope, id, *, db_instance_class, allow_major_version_upgrade=None, auto_minor_version_upgrade=None, availability_zone=None, db_cluster_identifier=None, db_instance_identifier=None, db_parameter_group_name=None, db_snapshot_identifier=None, db_subnet_group_name=None, preferred_maintenance_window=None, tags=None)

Bases: CfnResource

The AWS::Neptune::DBInstance type creates an Amazon Neptune DB instance.

Updating DB Instances

You can set a deletion policy for your DB instance to control how AWS CloudFormation handles the instance when the stack is deleted. For Neptune DB instances, you can choose to retain the instance, to delete the instance, or to create a snapshot of the instance. The default AWS CloudFormation behavior depends on the DBClusterIdentifier property:

For AWS::Neptune::DBInstance resources that don’t specify the DBClusterIdentifier property, AWS CloudFormation saves a snapshot of the DB instance.
For AWS::Neptune::DBInstance resources that do specify the DBClusterIdentifier property, AWS CloudFormation deletes the DB instance.

Deleting DB Instances .. epigraph:

If a DB instance is deleted or replaced during an update, AWS CloudFormation deletes all automated snapshots. However, it retains manual DB snapshots. During an update that requires replacement, you can apply a stack policy to prevent DB instances from being replaced.

When properties labeled Update requires: Replacement are updated, AWS CloudFormation first creates a replacement DB instance, changes references from other dependent resources to point to the replacement DB instance, and finally deletes the old DB instance. .. epigraph:

We highly recommend that you take a snapshot of the database before updating the stack. If you don't, you lose the data when AWS CloudFormation replaces your DB instance. To preserve your data, perform the following procedure:

- Deactivate any applications that are using the DB instance so that there's no activity on the DB instance.
- Create a snapshot of the DB instance.
- If you want to restore your instance using a DB snapshot, modify the updated template with your DB instance changes and add the ``DBSnapshotIdentifier`` property with the ID of the DB snapshot that you want to use.
- Update the stack.

Example:

# The code below shows an example of how to instantiate this type.
# The values are placeholders you should change.
from aws_cdk import aws_neptune as neptune

cfn_dBInstance = neptune.CfnDBInstance(self, "MyCfnDBInstance",
    db_instance_class="dbInstanceClass",

    # the properties below are optional
    allow_major_version_upgrade=False,
    auto_minor_version_upgrade=False,
    availability_zone="availabilityZone",
    db_cluster_identifier="dbClusterIdentifier",
    db_instance_identifier="dbInstanceIdentifier",
    db_parameter_group_name="dbParameterGroupName",
    db_snapshot_identifier="dbSnapshotIdentifier",
    db_subnet_group_name="dbSubnetGroupName",
    preferred_maintenance_window="preferredMaintenanceWindow",
    tags=[CfnTag(
        key="key",
        value="value"
    )]
)

Parameters:

scope (Construct) – Scope in which this resource is defined.
id (str) – Construct identifier for this resource (unique in its scope).
db_instance_class (str) – Contains the name of the compute and memory capacity class of the DB instance. If you update this property, some interruptions may occur.
allow_major_version_upgrade (Union[bool, IResolvable, None]) – Indicates that major version upgrades are allowed. Changing this parameter doesn’t result in an outage and the change is asynchronously applied as soon as possible. This parameter must be set to true when specifying a value for the EngineVersion parameter that is a different major version than the DB instance’s current version. When you change this parameter for an existing DB cluster, CloudFormation will replace your existing DB cluster with a new, empty one that uses the engine version you specified.
auto_minor_version_upgrade (Union[bool, IResolvable, None]) – Indicates that minor version patches are applied automatically. When updating this property, some interruptions may occur.
availability_zone (Optional[str]) – Specifies the name of the Availability Zone the DB instance is located in.
db_cluster_identifier (Optional[str]) – If the DB instance is a member of a DB cluster, contains the name of the DB cluster that the DB instance is a member of.
db_instance_identifier (Optional[str]) – Contains a user-supplied database identifier. This identifier is the unique key that identifies a DB instance.
db_parameter_group_name (Optional[str]) – The name of an existing DB parameter group or a reference to an AWS::Neptune::DBParameterGroup resource created in the template. If any of the data members of the referenced parameter group are changed during an update, the DB instance might need to be restarted, which causes some interruption. If the parameter group contains static parameters, whether they were changed or not, an update triggers a reboot.
db_snapshot_identifier (Optional[str]) – This parameter is not supported. AWS::Neptune::DBInstance does not support restoring from snapshots. AWS::Neptune::DBCluster does support restoring from snapshots.
db_subnet_group_name (Optional[str]) – A DB subnet group to associate with the DB instance. If you update this value, the new subnet group must be a subnet group in a new virtual private cloud (VPC).
preferred_maintenance_window (Optional[str]) – Specifies the weekly time range during which system maintenance can occur, in Universal Coordinated Time (UTC).
tags (Optional[Sequence[Union[CfnTag, Dict[str, Any]]]]) – An arbitrary set of tags (key-value pairs) for this DB instance.

Methods

add_deletion_override(path)

Syntactic sugar for addOverride(path, undefined).

Parameters:: path (str) – The path of the value to delete.
Return type:: None

add_dependency(target)

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.

Parameters:

target (CfnResource) –

Return type:

None

add_depends_on(target)

(deprecated) Indicates that this resource depends on another resource and cannot be provisioned unless the other resource has been successfully provisioned.

Parameters:

target (CfnResource) –

Deprecated:

use addDependency

Stability:

deprecated

Return type:

None

add_metadata(key, value)

Add a value to the CloudFormation Resource Metadata.

Parameters:

key (str) –
value (Any) –

See:

Return type:

None

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.

add_override(path, 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:

cfn_resource.add_override("Properties.GlobalSecondaryIndexes.0.Projection.NonKeyAttributes", ["myattribute"])
cfn_resource.add_override("Properties.GlobalSecondaryIndexes.1.ProjectionType", "INCLUDE")

would add the overrides Example:

"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.

Parameters:

path (str) –
- The path of the property, you can use dot notation to override values in complex types. Any intermediate keys will be created as needed.
value (Any) –
- The value. Could be primitive or complex.

Return type:

None

add_property_deletion_override(property_path)

Adds an override that deletes the value of a property from the resource definition.

Parameters:: property_path (str) – The path to the property.
Return type:: None

add_property_override(property_path, value)

Adds an override to a resource property.

Syntactic sugar for addOverride("Properties.<...>", value).

Parameters:

property_path (str) – The path of the property.
value (Any) – The value.

Return type:

None

apply_removal_policy(policy=None, *, apply_to_update_replace_policy=None, default=None)

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:

Parameters:

policy (Optional[RemovalPolicy]) –
apply_to_update_replace_policy (Optional[bool]) – Apply the same deletion policy to the resource’s “UpdateReplacePolicy”. Default: true
default (Optional[RemovalPolicy]) – The default policy to apply in case the removal policy is not defined. Default: - Default value is resource specific. To determine the default value for a resource, please consult that specific resource’s documentation.

See:

https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/aws-attribute-deletionpolicy.html#aws-attribute-deletionpolicy-options

Return type:

None

get_att(attribute_name, type_hint=None)

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.

Parameters:

attribute_name (str) – The name of the attribute.
type_hint (Optional[ResolutionTypeHint]) –

Return type:

Reference

get_metadata(key)

Static Methods

classmethod is_cfn_element(x)

Returns true if a construct is a stack element (i.e. part of the synthesized cloudformation template).

Uses duck-typing instead of instanceof to allow stack elements from different versions of this library to be included in the same stack.

Parameters:

x (Any) –

Return type:

bool

Returns:

The construct as a stack element or undefined if it is not a stack element.

classmethod is_cfn_resource(x)

Check whether the given object is a CfnResource.

Parameters:

x (Any) –

Return type:

bool

classmethod is_construct(x)

Checks if x is a construct.

Use this method instead of instanceof to properly detect Construct instances, even when the construct library is symlinked.

Explanation: in JavaScript, multiple copies of the constructs library on disk are seen as independent, completely different libraries. As a consequence, the class Construct in each copy of the constructs library is seen as a different class, and an instance of one class will not test as instanceof the other class. npm install will not create installations like this, but users may manually symlink construct libraries together or use a monorepo tool: in those cases, multiple copies of the constructs library can be accidentally installed, and instanceof will behave unpredictably. It is safest to avoid using instanceof, and using this type-testing method instead.

Parameters:: x (Any) – Any object.
Return type:: bool
Returns:: true if x is an object created from a class which extends Construct.
