Thomas Weise commented on APEXCORE-498:
---------------------------------------
[~sandesh] this is a good feature to have, it enables reprocessing. Can you
outline how it will work, without getting into code details for now.
Specifically, there are different areas where state is tracked (master, buffer
servers, operator state, external systems). How will this play with all of
those? Please consider end-to-end exactly once and see if and how the proposed
names checkpoints (also referred to as safepoints?) will fit in?
> Named Checkpoints - Checkpoint the DAG with a name/tag and start the app from
> that point
