> Issue Type: Improvement
> Components: Runtime / Coordination

> 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{}}}. See
> [Dispatcher#persistAndRunJob|https://github.com/apache/flink/blob/52cbeb90f32ca36c59590df1daa6748995c9b7f8/flink-runtime/src/main/java/org/apache/flink/runtime/dispatcher/Dispatcher.java#L645]
> as code reference.
> This Jira issue is about moving the job submission into the {{ioExecutor}} as
> an asynchronous call.
