    Description

      Right now, whenever a leader election is the newly-elected leader has to play back the log and rebuild its state, all the while being offline (the more task state transitions it has to play back, the longer this takes). Consider keeping this state available on the followers (consistent, but arbitrarily far behind) and then catching up after a successful leader election.
