Polling thread behaviour

Open ShivaKumarPeddi opened this issue 6 years ago • 0 comments

I have small doubt regarding how polling thread behaves.

Let us take a scenario where i have maxNumberOfMessages to be received per poll is 10. And We are using DEFAULT_WAIT_TIME = 20 seconds. I want to know how it behaves in different scenarios mentioned below.

  1. If there are 5-6 messages in queue. Then how many can be returned? And will polling thread wait for some time to get more messages?
  2. If there are no messages in queue, will it wait till it gets one messages or will it wait for more than that?
  3. If there are above 10 messages in queue, then how will it behave?

There are messages in queue and we expect them to be returned in at least 2-3 polls but that is not happening. And sometimes it is taking more than 10-15 polls. Within those 10-15 polls we don't see 10 messages received per poll at least once.
