Pavel Pereslegin updated IGNITE-22638:
--------------------------------------
Description:
To implement determination of the MinimalRequiredTime (IGNITE-22637), we need
to provide an API with semantics similar to
CheckpointListener#beforeCheckpointBegin (or afterCheckpointEnd, *to be
clarified*) to transiently save low watermark (timestamp), that guarantees that
when next time we'll apply the raft log, we don't need the history before that
timestamp.
This timestamp make sense only for groups (*clarify*) with persistence, but it
would be nice to have a common API (for example in MvPartitionStorage). So the
implementation requires collaboration with the storage engine team.
