     *   - 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.
     * - 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.
     *
     * > The `MessageDeduplicationId` is available to the consumer of the message (this can be useful for troubleshooting
     * > delivery issues).
     * >
     * > If a message is sent successfully but the acknowledgement is lost and the message is resent with the same
     * > `MessageDeduplicationId` after the deduplication interval, Amazon SQS can't detect duplicate messages.

     * To interleave multiple ordered streams within a single queue, use `MessageGroupId` values (for example, session data
