Example:
# The code below shows an example of how to instantiate this type. # The values are placeholders you should change. import aws_cdk.aws_dms as dms cfn_event_subscription = dms.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::DMS::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 Amazon 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
]) – Indicates whether to activate the subscription. If you don’t specify this property, AWS CloudFormation activates the subscription.event_categories (
Optional
[Sequence
[str
]]) – A list of event categories for a source type that you want to subscribe to. If you don’t specify this property, you are notified about all event categories. For more information, see Working with Events and Notifications in the AWS DMS User Guide .source_ids (
Optional
[Sequence
[str
]]) – A list of identifiers for which AWS DMS provides notification events. If you don’t specify a value, notifications are provided for all sources. If you specify multiple values, they must be of the same type. For example, if you specify a database instance ID, then all of the other values must be database instance IDs.source_type (
Optional
[str
]) – The type of AWS DMS resource that generates the events. For example, if you want to be notified of events generated by a replication instance, you set this parameter toreplication-instance
. If this value isn’t specified, all events are returned. Valid values :replication-instance
|replication-task
subscription_name (
Optional
[str
]) – The name of the AWS DMS event notification subscription. This name must be less than 255 characters.tags (
Optional
[Sequence
[CfnTag
]]) – One or more tags to be assigned to the event subscription.
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 prefixpath
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 toaddOverride
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: truedefault (
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
-
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)¶ Examines the CloudFormation resource and discloses attributes.
- Parameters
inspector (
TreeInspector
) –tree inspector to collect and process attributes.
- Return type
None

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