messageBody
The body of the message.
- Returns:
- The body of the message.
-
delaySeconds
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.When you set
FifoQueue
, you can't setDelaySeconds
per message. You can set this parameter only on a queue level.- Returns:

hasMessageAttributes
public final boolean hasMessageAttributes()For responses, this returns true if the service returned a value for the MessageAttributes property. This DOES NOT check that the value is non-empty (for which, you should check theisEmpty()
method on the property). This is useful because the SDK will never return a null collection or map, but you may need to differentiate between the service returning nothing (or null) and the service returning an empty collection or map. For requests, this returns true if a value for the property was specified in the request builder, and false if a value was not specified. -
messageAttributes
Each message attribute consists of a
Name
,Type
, andValue
. For more information, see Amazon SQS message attributes in the Amazon SQS Developer Guide.Attempts to modify the collection returned by this method will result in an UnsupportedOperationException.
This method will never return null. If you would like to know whether the service returned this field (so that you can differentiate between null and empty), you can use the
hasMessageAttributes()
method.- Returns:
- Each message attribute consists of a
Name
,Type
, andValue
. For more information, see Amazon SQS message attributes in the Amazon SQS Developer Guide.

messageSystemAttributes

Name

.-
Currently, the only supported message system attribute is
AWSTraceHeader
. Its type must beString
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.
Attempts to modify the collection returned by this method will result in an UnsupportedOperationException.
This method will never return null. If you would like to know whether the service returned this field (so that you can differentiate between null and empty), you can use the

messageDeduplicationId
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 sameMessageDeduplicationId
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 enableContentBasedDeduplication
for your queue, Amazon SQS uses a SHA-256 hash to generate theMessageDeduplicationId
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 haveContentBasedDeduplication
set, the action fails with an error. -
If the queue has
ContentBasedDeduplication
set, yourMessageDeduplicationId
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 aMessageDeduplicationId
that is the same as the one generated for the firstMessageDeduplicationId
, 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.Amazon SQS continues to keep track of the message deduplication ID even after the message is received and deleted.
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.- Returns:

messageGroupId
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 aMessageGroupId
, the action fails. -
ReceiveMessage
might return messages with multipleMessageGroupId
values. For eachMessageGroupId
, the messages are sorted by time sent. The caller can't specify aMessageGroupId
.
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.- Returns:
