zsq12138 commented on issue #7448: [hotfix][runtime] fix synchronous snapshots completed log URL: https://github.com/apache/flink/pull/7448#issuecomment-453059617 Thanks for review.I feel confused about why asynchronous checkpoints can have a synchronous part which can take > 0ms,and we can see that it just creates an object of AsyncSnapshotTask in this [method](https://github.com/apache/flink/blob/85dff904adb2b9fbe0588b3b68731af4970c28be/flink-runtime/src/main/java/org/apache/flink/runtime/state/DefaultOperatorStateBackend.java#L651), but it doesn't execute the method of run.
