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. -- This message was sent by Atlassian Jira (v8.20.1#820001)
