    * ContentBasedDeduplication - Enables content-based * deduplication. For more information, see Exactly-Once Processing in the Amazon SQS Developer Guide. *

    *
      *
    • *

      * Every message must have a unique MessageDeduplicationId, *

      *
        *
      • *

        * You may provide a MessageDeduplicationId explicitly. *

        *
        • *
      • *

        * If you aren't able to provide a MessageDeduplicationId and * you enable ContentBasedDeduplication for your queue, Amazon * SQS uses a SHA-256 hash to generate the * MessageDeduplicationId using the body of the message (but * not the attributes of the message). *

        *
        • *
      • *

        * If you don't provide a MessageDeduplicationId and the queue * doesn't have ContentBasedDeduplication set, the action fails * with an error. *

        *
        • *
      • *

        * If the queue has ContentBasedDeduplication set, your * MessageDeduplicationId overrides the generated one. *

        *
        • *
      *
      • *
    • *

      * When ContentBasedDeduplication is in effect, messages with * identical content sent within the deduplication interval are treated as * duplicates and only one copy of the message is delivered. *

      *
      • *
    • *

      * You can also use ContentBasedDeduplication for messages with * identical content to be treated as duplicates. *

      *
      • *
    • *

      * If you send one message with ContentBasedDeduplication * enabled and then another message with a * MessageDeduplicationId that is the same as the one generated * for the first MessageDeduplicationId, the two messages are * treated as duplicates and only one copy of the message is delivered. *

* Any other valid special request parameters that are specified (such as * ApproximateNumberOfMessages, * ApproximateNumberOfMessagesDelayed, * ApproximateNumberOfMessagesNotVisible, * CreatedTimestamp, LastModifiedTimestamp, and * QueueArn) will be ignored. *
