[jira] [Commented] (KAFKA-4560) Min / Max Partitions Fetch Records params

    [ https://issues.apache.org/jira/browse/KAFKA-4560?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15762931#comment-15762931 ] 

huxi commented on KAFKA-4560:
-----------------------------

There is a consumer config named "max.poll.records" that controls the maximum number of records returned in a single call to poll(). Is that what you want?

> There is currently a `max.partition.fetch.bytes` parameter to limit the total size of the fetch call (also a min).
> Sometimes I'd like to control how many records altogether I'm getting at the time and I'd like to see a `max.partition.fetch.records` (also a min).
> If both are specified the first condition that is met would complete the fetch call.
