#delay_seconds ⇒ Integer

The length of time, in seconds, for which a specific message is delayed. Valid values: 0 to 900. Maximum: 15 minutes. Messages with a positive ‘DelaySeconds` value become available for processing after the delay period is finished. If you don’t specify a value, the default value for the queue is applied.

<note markdown=“1”> When you set ‘FifoQueue`, you can’t set ‘DelaySeconds` per message. You can set this parameter only on a queue level.

Returns:

  • (Integer)

end

#message_deduplication_id ⇒ String

This parameter applies only to FIFO (first-in-first-out) queues.

The token used for deduplication of messages within a 5-minute minimum deduplication interval. If a message with a particular ‘MessageDeduplicationId` is sent successfully, subsequent messages with the same `MessageDeduplicationId` are accepted successfully but aren’t delivered. 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.

  • 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.

<note markdown=“1”> 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.

Amazon SQS continues to keep track of the message deduplication ID

even after the message is received and deleted.

</note>

The length of ‘MessageDeduplicationId` is 128 characters. `MessageDeduplicationId` can contain alphanumeric characters (`a-z`, `A-Z`, `0-9`) and punctuation (“ !“#$%&’()*+,-./:;<=>?@[]^_`{|}~ “).

For best practices of using ‘MessageDeduplicationId`, see [Using the MessageDeduplicationId Property] in the *Amazon SQS Developer Guide*.

end

#message_group_id ⇒ String

This parameter applies only to FIFO (first-in-first-out) queues.

The tag that specifies that a message belongs to a specific message group. Messages that belong to the same message group are processed in a FIFO manner (however, messages in different message groups might be processed out of order). To interleave multiple ordered streams within a single queue, use ‘MessageGroupId` values (for example, session data for multiple users). In this scenario, multiple consumers can process the queue, but the session data of each user is processed in a FIFO fashion.

  • You must associate a non-empty ‘MessageGroupId` with a message. If you don’t provide a ‘MessageGroupId`, the action fails.

  • ‘ReceiveMessage` might return messages with multiple `MessageGroupId` values. For each `MessageGroupId`, the messages are sorted by time sent. The caller can’t specify a ‘MessageGroupId`.

The length of ‘MessageGroupId` is 128 characters. Valid values: alphanumeric characters and punctuation “ (!“#$%&’()*+,-./:;<=>?@[]^_`{|}~) “.

For best practices of using ‘MessageGroupId`, see [Using the MessageGroupId Property] in the *Amazon SQS Developer Guide*.

‘MessageGroupId` is required for FIFO queues. You can’t use it for Standard queues.

#message_system_attributes ⇒ Hash<String,Types::MessageSystemAttributeValue>

The message system attribute to send Each message system attribute consists of a ‘Name`, `Type`, and `Value`.

  • Currently, the only supported message system attribute is ‘AWSTraceHeader`. Its type must be `String` and its value must be a correctly formatted X-Ray trace header string.

  • The size of a message system attribute doesn’t count towards the total size of a message.
