[FLINK-33500][Runtime] Run storing the JobGraph an asynchronous operation
What is the purpose of the change
Currently, submitting a job starts with storing the JobGraph (in HA setups) in the JobGraphStore. This includes writing the file to S3 (or some other remote file system). The job submission is done in the Dispatcher's main thread. If writing the JobGraph is slow, it would block any other operation on the Dispatcher.
Brief change log
- The dispatcher put JobGraph asynchronously in ioExecutor
- The dispatcher write To ExecutionGraphInfoStore asynchronously in ioExecutor
- The JobGraphWriter interface class adds a putJobGraphAsync method for asynchronous write operations
- Implementation class DefaultJobGraphStore adds the putJobGraphAsync method for asynchronous write operations
Verifying this change
This change added tests and can be verified as follows:
- Added the Dispatcher JobSubmission test, use ZooKeeperStateHandleStore as JobGraphStore
- Added the Dispatcher JobSubmission test, use KubernetesStateHandleStore as JobGraphStore
