Summary: [Changelog] Deadlock in FsStateChangelogWriter
Key: FLINK-26592
URL: https://issues.apache.org/jira/browse/FLINK-26592
Project: Flink
Issue Type: Bug
Components: Runtime / State Backends
Affects Versions: 1.15.0
Reporter: Roman Khachatryan
Assignee: Roman Khachatryan
Fix For: 1.16.0
The issue occurs when sizes of buffers are set to minimum (e.g. 1 byte).
Task thread tries to update state -> schedules to upload changes -> waits for
capacity.
Upload threads do release capacity on upload completion; however, they are
unable to send back the results because the Writer lock is taken; therefore,
they're unable to proceed with the next uploads.
