Summary: Fire timers when window state is currently empty Key: FLINK-5363 URL: https://issues.apache.org/jira/browse/FLINK-5363 Project: Flink Issue Type: Bug Components: Streaming Reporter: Aljoscha Krettek Assignee: Aljoscha Krettek Fix For: 1.2.0 Currently, when a {{Trigger}} sets a timer and that timer fires in the future at a point when there is currently no data in the window state, then that timer is being ignored. This is a problem for some users because they manually set cleanup timers and they need to be called because the trigger needs to cleanup some state. (For normal time windows this is not a problem, but for special cases built on top of {{GlobalWindows}} the current behaviour leads to problems.) -- This message was sent by Atlassian JIRA (v6.3.4#6332)
