Could you elaborate a little bit on what you refactored and which
components would be important to review?
> Add support for JobSessions
> ---------------------------
>
> Key: FLINK-2097
> URL: https://issues.apache.org/jira/browse/FLINK-2097
> Project: Flink
> Issue Type: Sub-task
> Components: JobManager
> Affects Versions: 0.9
> Reporter: Stephan Ewen
> Assignee: Maximilian Michels
> Fix For: 0.10
>
>
> 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
