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.
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. This property applies only to server-side-encryption.
Version of the Amazon SNS signature used. If the SignatureVersion is 1, Signature is a Base64-encoded SHA1withRSA signature of the Message, MessageId, Type, Timestamp, and TopicArn values. If the SignatureVersion is 2, Signature is a Base64-encoded SHA256withRSA signature of the Message, MessageId, Type, Timestamp, and TopicArn values.
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.
