------------------------------------
Summary: Consumer.poll(0)'s overhead too large
Key: KAFKA-2655
URL: https://issues.apache.org/jira/browse/KAFKA-2655
Project: Kafka
Issue Type: Sub-task
Reporter: Guozhang Wang
Assignee: Jason Gustafson
Fix For: 0.9.0.1
Currently with a single partition, even if it is paused, calling poll(0) could
still be costing as much as 1ms since it triggers a few system calls. Some of
those can possibly be optimized away.
