Yan Xu commented on MESOS-715:
------------------------------

OK we imagine there could be a background "filler" that does the job in a way similar to the
catch up process and *with best effort* keep all replicas up-to-date.

> If a framework has a leader election, the newly elected leader needs to re-play the log
of task transitions to build up the state of the world. It would help frameworks failover
much faster if followers were able to read the log to keep themselves primed to take over.
