--------------------------------------
Summary: Potential memory leaks in SourceOperator
Key: FLINK-25827
URL: https://issues.apache.org/jira/browse/FLINK-25827
Project: Flink
Issue Type: Sub-task
Components: Runtime / Task
Affects Versions: 1.14.3, 1.15.0
Reporter: Piotr Nowojski
Fix For: 1.15.0, 1.14.4
{{SourceOperator.SourceOperatorAvailabilityHelper}} is prone to the same type
of memory leak as FLINK-25728. Every time new CompletableFuture.any is created:
{code:java}
currentCombinedFuture =
CompletableFuture.anyOf(forcedStopFuture,
sourceReaderFuture);
return currentCombinedFuture;
{code}
Such future is never garbage collected, because {{forcedStopFuture}} will keep
a reference to it. This will eventually lead to a memory leak, or force
stopping might take very long time to complete.
