attributes property

Map<String, String>? attributes
final

A map of the topic's attributes. Attributes in this map include the following:

  • DeliveryPolicy – The JSON serialization of the topic's delivery policy.
  • DisplayName – The human-readable name used in the From field for notifications to email and email-json endpoints.
  • Owner – The AWS account ID of the topic's owner.
  • Policy – The JSON serialization of the topic's access control policy.
  • SubscriptionsConfirmed – The number of confirmed subscriptions for the topic.
  • SubscriptionsDeleted – The number of deleted subscriptions for the topic.
  • SubscriptionsPending – The number of subscriptions pending confirmation for the topic.
  • TopicArn – The topic's ARN.
  • EffectiveDeliveryPolicy – The JSON serialization of the effective delivery policy, taking system defaults into account.
The following attribute applies only to server-side-encryption:
  • KmsMasterKeyId - 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 in the AWS Key Management Service API Reference.
The following attributes apply only to FIFO topics:
  • FifoTopic – When this is set to true, a FIFO topic is created.
  • ContentBasedDeduplication – 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.
