Biao Liu created FLINK-13905: -------------------------------- Summary: Separate checkpoint triggering into stages Key: FLINK-13905 URL: https://issues.apache.org/jira/browse/FLINK-13905 Project: Flink Issue Type: Sub-task Components: Runtime / Coordination Reporter: Biao Liu Fix For: 1.10.0
Currently {{CheckpointCoordinator#triggerCheckpoint}} includes some heavy IO operations. We plan to separate the triggering into different stages. The IO operations are executed in IO threads, while other on-memory operations are not. This is a preparation for making all on-memory operations of {{CheckpointCoordinator}} single threaded (in main thread). Note that we could not put on-memory operations of triggering into main thread directly now. Because there are still some operations on a heavy lock (coordinator-wide). -- This message was sent by Atlassian Jira (v8.3.2#803003)
