Hi,

I ran the following test

1) I created 1 Queue
2) Registered 2 consumers to the queue
3) Enqueued 10 messages to the Queue. [ The first enqueued message is long
running. I simulated such that the first message on consumption takes about
50 seconds to be processed]
4) Once the enqueue is committed, the 2 consumers each pick a message.
5) The 1st consumer that got the long running message works on it for a long
time while the second consumer that got the second message keeps processing
and going to the next message, but  only goes as far until it processes 5 of
the 10 messages enqueued. Then the 2nd consumer gives up processing.
6) When the 1st consumer with the  long running message completes, it then
ends up processing the remaining messages and my test completes.

So it seems like the two consumers were trying to take a fair share of
messages that they were processing immaterial of the time it takes to
process individual messages. Enqueued message = 10, Consumer 1 share of 5
messages were processed by it, and Consumer 2's share of 5 messages were
processed by it.


This is kinda against the behavior that I'd like to see. The desired
behavior in my case is that of each consumer keeps going on if it's done and
has other messages to process.

In the above test, I'd expect as consumer 1 is working on the long message,
the second consumer should work its way through all the remaining messages.

Is there some config that I'm missing that could cause this effect?? Any
advice on tackling this will be great.

Also, Can someone please explain in what order are messages delivered to the
consumers in the following cases?

Case 1)
 There is a single Queue with more than 1 message in it and multiple
consumers registered to it.

Case 2)
There are multiple queues each with more than 1 message in it, and has
multiple consumers registered to it.



Thank you,
