[−][src]Struct rusoto_sqs::SendMessageRequest
Fields
delay_seconds: Option<i64>
The length of time, in seconds, for which to delay a specific message. 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 applies.
When you set FifoQueue
, you can't set DelaySeconds
per message. You can set this parameter only on a queue level.
message_attributes: Option<HashMap<String, MessageAttributeValue>>
Each message attribute consists of a Name
, Type
, and Value
. For more information, see Amazon SQS Message Attributes in the Amazon Simple Queue Service Developer Guide.
message_body: String
The message to send. The maximum string size is 256 KB.
A message can include only XML, JSON, and unformatted text. The following Unicode characters are allowed:
#x9
| #xA
| #xD
| #x20
to #xD7FF
| #xE000
to #xFFFD
| #x10000
to #x10FFFF
Any characters not included in this list will be rejected. For more information, see the W3C specification for characters.
message_deduplication_id: Option<String>
This parameter applies only to FIFO (first-in-first-out) queues.
The token used for deduplication of sent messages. If a message with a particular MessageDeduplicationId
is sent successfully, any messages sent with the same MessageDeduplicationId
are accepted successfully but aren't delivered during the 5-minute deduplication interval. For more information, see Exactly-Once Processing in the Amazon Simple Queue Service 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 maximum 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 Simple Queue Service Developer Guide.
message_group_id: Option<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 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 Simple Queue Service Developer Guide.
MessageGroupId
is required for FIFO queues. You can't use it for Standard queues.
message_system_attributes: Option<HashMap<String, 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 beString
and its value must be a correctly formatted AWS X-Ray trace header string. -
The size of a message system attribute doesn't count towards the total size of a message.
queue_url: String
The URL of the Amazon SQS queue to which a message is sent.
Queue URLs and names are case-sensitive.
