问题
I would like to send 1000 messages and retransmit only those that failed. Is there any way?
Are there any methods to identify each failed message, such as a unique message ID?
As you can see, there is no identifiable message ID.
Is actually possible that only one message should be resent as in this case? Should I resend only this message or all the bulk?
Should I use Exponential Backoff? Then, Where can I find example source?
