[jira] [Updated] (KAFKA-2655) Consumer.poll(0)'s overhead too large

     [ https://issues.apache.org/jira/browse/KAFKA-2655?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Ismael Juma updated KAFKA-2655:
-------------------------------
    Fix Version/s:     (was: 0.9.0.1)

> 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

> 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.
