Review Comment:
I am thinking if we can add an entry to HoodieRestorePlan (avro model) to
store the savepoint commit timestamp only. that would make life easier.

Review Comment:
why just check for lastInstant. it can be anything right.

Review Comment:
not sure if we can do this. we can just delete the inflight and make
progress. we don't want to requested to be overwritten just incase.
