[jira] [Commented] (FLINK-3439) Remove final Long.MAX_VALUE Watermark in StreamSource

    [ https://issues.apache.org/jira/browse/FLINK-3439?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15152096#comment-15152096 ] 

Stephan Ewen commented on FLINK-3439:
-------------------------------------

Just be make sure I get this correctly:
  - Regular sources do not emit a MAX_LONG watermark at the end
  - Sources that we know will never have data emit one immediately

Is that what you have in mind?

> I think this was an oversight. At one point we decided to not emit in-flight windows when closing the topology or sources.
