> Today the source table's cardinality calculation is a synced action which
> need be taken by the admin; The action will trigger a map-reduce job and
> blocks the user's action. If the hive table is small that is okay, but if it
> is a big table, the job may take tens of minutes to finish, that is not user
> friendly.
> With the generic job flow engine be released, the cardinality calculation
> should be able to converted to a backend job, so user doesn't need be hold on
> UI.
