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.
