SendMessageBatch
Method for simultaneously delivering up to 10 messages to the specified queue. When sending messages to a FIFO queue, they will be delivered in the sending order.
The sending action results are reported individually for each message. Check all the results, because the send message batch action may fail even if code 200 is returned in response to the SendMessageBatch method call. A message can include XML, JSON, and unformatted text. The following Unicode characters are supported:
#x9#xA#xD- From
#x20to#xD7FF - From
#xE000to#xFFFD - From
#x10000to#x10FFFFF
The maximum batch size is 256 KB.
If the DelaySeconds parameter is not specified for a batch message, the default queue value will be used.
