[jira] [Commented] (FLINK-16787) Provide an assigner strategy of average splits allocation

    [ https://issues.apache.org/jira/browse/FLINK-16787?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17069927#comment-17069927 ] 

Zhijiang commented on FLINK-16787:
----------------------------------

I guess this feature would be involved in more components, from API to coordinator and then task stack in batch mode, maybe need a FLIP. And I do not think it can be done in release-1.11.  So I adjust the related labels above.

> For now InputSplitAssigner:
> Each task is to grab split, rather than average distribution, so once the later tasks are not scheduled, the former tasks will grab all splits.
> We can provide an assigner strategy of average splits allocation.
