>
> The current trigger design is simplistic and keeps all the intermediate state
> in memory. But this presents two problems when the overseer itself fails:
> # We lose tracking state such as which node was added before the overseer
> restarted
> # A nodeLost trigger can never really fire for the overseer node itself
> So we need a way, preferably in the trigger API itself to save intermediate
> state or checkpoints so that it can seamlessly continue on overseer restarts.
