Concurrent consumers got same task from queue #46

Closed dmitry-sobolev closed 7 years ago

dmitry-sobolev commented 7 years ago

Hello,

I've tried to create system with one producer and 5 consumers using tarantool queue and later i've noticed that sometimes two workers getting same task. Is there a way to avoid this issue or I just should use another queue for my purposes?

Please provide more details about the problem. Are you using a single master or multi-master set up? Do you use task timeouts? A reproducible test case would be perfect. If you did everything right, you'd never have two workers getting the same task.

I'm using single master and not using timeouts. I am working on test case.

Yes.

Maybe you hadn't ack'ed tasks or used release or have client disconnections?

I've ack'ed them, but yes maybe I have disconnection. I'll try to investigate this case.

It seems like these errors were result of errors in my code
