> Currently, Flink session cluster uses FileArchivedExecutionGraphStore to keep
> finished jobs for historic requests. The FileArchivedExecutionGraphStore
> purges archived ExecutionGraphs only by an expiration time. In a session
> cluster on which runs many batch jobs, it is hard to config the
> jobstore.expiration-time, if configured too short, the historical information
> may have been deleted when the user want to check it, and if configured too
> long, the web front end may response very slowly when the number of finished
> job is too large. We'd better add a new config option to allow config of the
> maximum capacity of the FileArchivedExecutionGraphStore, which is well
> supported by Guava Cache. Then we can set the expiration time to a relative
> long value and set the maximum capacity to an appropriate value which does
> not make the web ui become too slow.
