ASF GitHub Bot updated FLINK-14344: ----------------------------------- Labels: pull-request-available (was: ) > Snapshot master hook state asynchronously > ----------------------------------------- > > Key: FLINK-14344 > URL: https://issues.apache.org/jira/browse/FLINK-14344 > Project: Flink > Issue Type: Sub-task > Components: Runtime / Checkpointing > Reporter: Biao Liu > Assignee: Biao Liu > Priority: Major > Labels: pull-request-available > Fix For: 1.10.0 > > > Currently we snapshot the master hook state synchronously. As a part of > reworking threading model of {{CheckpointCoordinator}}, we have to make this > non-blocking to satisfy the requirement of running in main thread. > The behavior of snapshotting master hook state is similar to task state > snapshotting. Master state snapshotting is taken before task state > snapshotting. Because in master hook, there might be external system > initialization which task state snapshotting might depend on. -- This message was sent by Atlassian Jira (v8.3.4#803005)
