Mark Shields updated BEAM-175: ------------------------------ Summary: Don't leak garbage collection timers in GlobalWindow (was: Leak garbage collection timers in GlobalWindow) > Don't leak garbage collection timers in GlobalWindow > ---------------------------------------------------- > > Key: BEAM-175 > URL: https://issues.apache.org/jira/browse/BEAM-175 > Project: Beam > Issue Type: Bug > Components: runner-core > Reporter: Mark Shields > Assignee: Mark Shields > > Consider the transform: > Window > .into(new GlobalWindows()) > .triggering( > Repeatedly.forever( > AfterProcessingTime.pastFirstElementInPane().plusDelayOf(...))) > .discardingFiredPanes() > This is a common idiom for 'process elements bunched by arrival time'. > Currently we create an end-of-window timer per key, which clearly will only > fire if the pipeline is drained. > Better would be to avoid creating end-of-window timers if there's no state > which needs to be processed at end-of-window (ie at drain if the Global > window). -- This message was sent by Atlassian JIRA (v6.3.4#6332)
