Subject [jira] [Commented] (FLINK-3669) WindowOperator registers a lot of timers at StreamTask
Date Wed, 27 Apr 2016 16:31:13 GMT

    [ https://issues.apache.org/jira/browse/FLINK-3669?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15260431#comment-15260431

Konstantin Knauf commented on FLINK-3669:
-----------------------------------------

I made the changes as suggested, and will open a PR after the travis build later this evening.


Unfortunately, I will not be able to test it with the original application (customer code).

I could try to reproduce the issue locally and test it with the new version, but this will
take at least till next weekend as I can only do that on my own time.

> Right now, the WindowOperator registers a timer at the StreamTask for every processing-time
timer that a Trigger registers. We should combine several registered trigger timers to only
register one low-level timer (timer coalescing).
