> Sessions make sure that the JobManager does not immediately discard a JobGraph after execution, but keeps it around for further operations to be attached to the graph. By keeping the JobGraph around, the cached streams (intermediate data) are also kept,
> That is the way of realizing interactive sessions on top of a streaming dataflow abstraction.
> ExecutionGraphs should be kept as long as
> - no timeout occurred or
> - the session has not been explicitly ended
