Hanisha Koneru commented on RATIS-624:
--------------------------------------
The requirement comes from Ozone. In Ozone, if one of the OM Ratis server is
lagging behind and needs to install a snapshot to catch up, it would have to
stop it's Ratis server so that there are no transactions applied in the
meanwhile. If Ratis provides an option to pause/ unpause its state, OM Ratis
server would not have to be stopped in this process.
> RaftServer should support pause/ unpause in its LifeCycle state
