Ismael Juma commented on KAFKA-2655: ------------------------------------ It would be good to get some actual numbers before we try to optimise. JMH recommend. > 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 > Components: consumer > 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. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
