ifndef-SleePy commented on issue #9885: [FLINK-14344][checkpointing] Snapshots master hook state asynchronously URL: https://github.com/apache/flink/pull/9885#issuecomment-547288245 @pnowojski , I have rebased master branch. The PR is based on such assumptions: 1. Keeps the compatibility of `MasterTriggerRestoreHook.triggerCheckpoint` 2. `MasterTriggerRestoreHook.triggerCheckpoint` will be executed in main thread eventually. So there should not be any heavy operation executed synchronously. The assumptions might not be the final decision. But I believe it probably help us to find the best choice.
