Example:

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

cfn_event_subscription = rds.CfnEventSubscription(self, "MyCfnEventSubscription",
    sns_topic_arn="snsTopicArn",

    # the properties below are optional
    enabled=False,
    event_categories=["eventCategories"],
    source_ids=["sourceIds"],
    source_type="sourceType",
    subscription_name="subscriptionName",
    tags=[CfnTag(
        key="key",
        value="value"
    )]
)

Create a new AWS::RDS::EventSubscription.

Parameters
  • scope (Construct) –

    • scope in which this resource is defined.

  • id (str) –

    • scoped id of the resource.

  • sns_topic_arn (str) – The Amazon Resource Name (ARN) of the SNS topic created for event notification. The ARN is created by Amazon SNS when you create a topic and subscribe to it.

  • enabled (Union[bool, IResolvable, None]) – A value that indicates whether to activate the subscription. If the event notification subscription isn’t activated, the subscription is created but not active.

  • event_categories (Optional[Sequence[str]]) – A list of event categories for a particular source type ( SourceType ) that you want to subscribe to. You can see a list of the categories for a given source type in the “Amazon RDS event categories and event messages” section of the *Amazon RDS User Guide* or the *Amazon Aurora User Guide* . You can also see this list by using the DescribeEventCategories operation.

  • source_ids (Optional[Sequence[str]]) – The list of identifiers of the event sources for which events are returned. If not specified, then all sources are included in the response. An identifier must begin with a letter and must contain only ASCII letters, digits, and hyphens. It can’t end with a hyphen or contain two consecutive hyphens. Constraints: - If a SourceIds value is supplied, SourceType must also be provided. - If the source type is a DB instance, a DBInstanceIdentifier value must be supplied. - If the source type is a DB cluster, a DBClusterIdentifier value must be supplied. - If the source type is a DB parameter group, a DBParameterGroupName value must be supplied. - If the source type is a DB security group, a DBSecurityGroupName value must be supplied. - If the source type is a DB snapshot, a DBSnapshotIdentifier value must be supplied. - If the source type is a DB cluster snapshot, a DBClusterSnapshotIdentifier value must be supplied.

  • source_type (Optional[str]) – The type of source that is generating the events. For example, if you want to be notified of events generated by a DB instance, set this parameter to db-instance . If this value isn’t specified, all events are returned. Valid values: db-instance | db-cluster | db-parameter-group | db-security-group | db-snapshot | db-cluster-snapshot

  • subscription_name (Optional[str]) – AWS::RDS::EventSubscription.SubscriptionName.

  • tags (Optional[Sequence[Union[CfnTag, Dict[str, Any]]]]) – AWS::RDS::EventSubscription.Tags.

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_depends_on(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_metadata(key, value)

Add a value to the CloudFormation Resource Metadata.

Parameters
  • key (str) –

  • value (Any) –

See

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.

Return type

None

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 intermdediate 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).

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 resoure, please consult that specific resource’s documentation.

Return type

None

get_att(attribute_name)

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.

Return type

Reference

get_metadata(key)

Retrieve a value value from the CloudFormation Resource Metadata.

Parameters

key (str) –

See

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.

Return type

Any

inspect(inspector)

Parameters

inspector (TreeInspector) –

  • tree inspector to collect and process attributes.

Return type
