-----------------------------------------
Summary: ContinuousEventTimeTrigger doesn't fire at the end of the
window
Key: FLINK-5149
URL: https://issues.apache.org/jira/browse/FLINK-5149
Project: Flink
Issue Type: Bug
Components: Streaming
Affects Versions: 1.1.3
Reporter: Maximilian Michels
Assignee: Maximilian Michels
Fix For: 1.2.0
The ContinuousEventTimeTrigger registers a timer when elements arrive. The
timers might be registered past the end of the window. In this case, the window
is cleaned up and doesn't fire at all. That is certainly not what users have in
mind when they use the custom trigger.
I proposed to let it behave like a normal EventTimeTrigger in addition to its
continuous firing capabilities. So it should fire at the end of the window
regardless of timers set.
