        value="value"
    )],
    topic_name="topicName",
    tracing_config="tracingConfig"
)

Create a new AWS::SNS::Topic.

Parameters:

scope (Construct) –
- scope in which this resource is defined.
id (str) –
- scoped id of the resource.
content_based_deduplication (Union[bool, IResolvable, None]) – Enables content-based deduplication for FIFO topics. - By default, ContentBasedDeduplication is set to false . If you create a FIFO topic and this attribute is false , you must specify a value for the MessageDeduplicationId parameter for the Publish action. - When you set ContentBasedDeduplication to true , Amazon SNS uses a SHA-256 hash to generate the MessageDeduplicationId using the body of the message (but not the attributes of the message). (Optional) To override the generated value, you can specify a value for the the MessageDeduplicationId parameter for the Publish action.
data_protection_policy (Optional[Any]) – The body of the policy document you want to use for this topic. You can only add one policy per topic. The policy must be in JSON string format. Length Constraints: Maximum length of 30,720.
display_name (Optional[str]) – The display name to use for an Amazon SNS topic with SMS subscriptions. The display name must be maximum 100 characters long, including hyphens (-), underscores (_), spaces, and tabs.
fifo_topic (Union[bool, IResolvable, None]) – Set to true to create a FIFO topic.
kms_master_key_id (Optional[str]) – The ID of an AWS managed customer master key (CMK) for Amazon SNS or a custom CMK. For more information, see Key terms . For more examples, see [KeyId](https://docs.aws.amazon.com/kms/latest/APIReference/API_DescribeKey.html#API_DescribeKey_RequestParameters) in the AWS Key Management Service API Reference . This property applies only to server-side-encryption .
signature_version (Optional[str]) – The signature version corresponds to the hashing algorithm used while creating the signature of the notifications, subscription confirmations, or unsubscribe confirmation messages sent by Amazon SNS. By default, SignatureVersion is set to 1 .
subscription (Union[IResolvable, Sequence[Union[IResolvable, SubscriptionProperty, Dict[str, Any]]], None]) – The Amazon SNS subscriptions (endpoints) for this topic. .. epigraph:: If you specify the Subscription property in the AWS::SNS::Topic resource and it creates an associated subscription resource, the associated subscription is not deleted when the AWS::SNS::Topic resource is deleted.
tags (Optional[Sequence[Union[CfnTag, Dict[str, Any]]]]) – The list of tags to add to a new topic. .. epigraph:: To be able to tag a topic on creation, you must have the sns:CreateTopic and sns:TagResource permissions.
topic_name (Optional[str]) – The name of the topic you want to create. Topic names must include only uppercase and lowercase ASCII letters, numbers, underscores, and hyphens, and must be between 1 and 256 characters long. FIFO topic names must end with .fifo . If you don’t specify a name, AWS CloudFormation generates a unique physical ID and uses that ID for the topic name. For more information, see Name type . .. epigraph:: If you specify a name, you can’t perform updates that require replacement of this resource. You can perform updates that require no or some interruption. If you must replace the resource, specify a new name.
tracing_config (Optional[str]) – Tracing mode of an Amazon SNS topic. By default TracingConfig is set to PassThrough , and the topic passes through the tracing header it receives from an SNS publisher to its subscriptions. If set to Active , SNS will vend X-Ray segment data to topic owner account if the sampled flag in the tracing header is true. Only supported on standard topics.

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:

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 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:

Return type:

Any

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)

Examines the CloudFormation resource and discloses attributes.

Parameters:

inspector (TreeInspector) –

tree inspector to collect and process attributes.

Return type:

None

override_logical_id(new_logical_id)

By default, ContentBasedDeduplication is set to false . If you create a FIFO topic and this attribute is false , you must specify a value for the MessageDeduplicationId parameter for the Publish action.
When you set ContentBasedDeduplication to true , Amazon SNS uses a SHA-256 hash to generate the MessageDeduplicationId using the body of the message (but not the attributes of the message).

(Optional) To override the generated value, you can specify a value for the the MessageDeduplicationId parameter for the Publish action.
