For retries, the space between retry attempts increments at different intervals.

 

Example: the first attempt will be once after 1 minute, then second attempt will retry twice for every 5 minutes, after that the third attempt will retry six times for every consecutive 30 minutes and lastly will retry after the following 12 hours.

 

If the subscriber becomes available within the retry process, the message will be delivered.

 

If the subscriber remains unavailable, the retry process will continue until it completes the cycle, and will result in the message(s) expiring.
