Send Message Batch
sqs_send_message_batch | R Documentation |
You can use SendMessageBatch to send up to 10 messages to the specified queue by assigning either identical or different values to each message (or by not assigning values at all)¶
Description¶
You can use send_message_batch
to send up to 10 messages to the
specified queue by assigning either identical or different values to
each message (or by not assigning values at all). This is a batch
version of SendMessage.
For a FIFO queue, multiple messages within a
single batch are enqueued in the order they are sent.
The result of sending each message is reported individually in the
response. Because the batch request can result in a combination of
successful and unsuccessful actions, you should check for batch errors
even when the call returns an HTTP status code of 200
.
The maximum allowed individual message size and the maximum total payload size (the sum of the individual lengths of all of the batched messages) are both 256 KiB (262,144 bytes).
A message can include only XML, JSON, and unformatted text. The following Unicode characters are allowed. For more information, see the W3C specification for characters.
#x9
| #xA
| #xD
| #x20
to #xD7FF
| #xE000
to #xFFFD
|
#x10000
to #x10FFFF
Amazon SQS does not throw an exception or completely reject the message
if it contains invalid characters. Instead, it replaces those invalid
characters with U+FFFD
before storing the message in the queue, as
long as the message body contains at least one valid character.
If you don't specify the DelaySeconds
parameter for an entry, Amazon
SQS uses the default value for the queue.
