> The TaskExecutor has to track which partitions it has stored, grouped by JobID.
> This is necessary so that the TaskExecutor only disconnects from the JobManager if it no longer stores relevant (i.e., belonging to the corresponding job) partitions (similar to the taskSlotTable).
> Additionally this is needed so that the TaskExecutor can independently cleanup partitions for a given job if the connection to the corresponding JobManager is lost.
