----------------------------------
Summary: StreamingDataflowWorker ReaderCache performs blocking
close of readers on possibly important threads
Key: BEAM-11401
URL: https://issues.apache.org/jira/browse/BEAM-11401
Project: Beam
Issue Type: Bug
Components: runner-dataflow
Reporter: Sam Whittle
Assignee: Sam Whittle
Currently closing can be performed when acquiring an unrelated reader, caching
an unrelated reader, or invalidating readers.
Such closing could be performed in the background to ensure that it doesn't
block unrelated processing or important threads (such as grpc commit stream).
