Subject Re: New consumer API waits indefinitely
Date Mon, 04 Apr 2016 06:51:48 GMT

Check following threads;

   - If my producer producing, then why the consumer couldn't consume? it
   stuck @ poll()
   - Consumer thread is waiting forever, not returning any objects


I think new APIs are recommended.
