Review comment:
So this is user to update a customized state for a certain partition. I
don't think we have the knowledge to clean up stale states, meaning if the user
only update "CURRENT_STATE" of customized state, we update it, and keep the
other fields unchanged. If they would like to do a full update, they will use
the other API and provide the full map, and the original map will be
overwritten.
