Subject [jira] [Commented] (FLINK-4692) Add tumbling and sliding group-windows for batch tables
Date Thu, 10 Nov 2016 03:16:58 GMT

    [ https://issues.apache.org/jira/browse/FLINK-4692?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15652869#comment-15652869

Jark Wu commented on FLINK-4692:

Yes. I agree to move the sliding window to a separate issue. And we can discuss the implementation
more detail in that issue.

Option 2 is a nicer way but only support combinable aggregation. Maybe we can implement approach-1
in the first version, and do improvement in the later issues.
