> Currently, if there are thousands of eligible  coordinator actions  to be created (e.g. catch-up mode) for one coordinator job, oozie creates all of them once and overloading the system.
> This thing needs to be controlled and should only materialized X number of active actions per coordinator job. The
> value of X should be configurable whether in oozie level or per job level that needs to be decided. 
> In addition, there should be a way for customer to define the order by which job creation should be followed.  For
> example, if there are 1000 actions ready to be created which X actions should be created first. Such as FIFO or LIFO.
> This will definitely reduce the load on the internal queue.
