> Key: IGNITE-22638
> URL: https://issues.apache.org/jira/browse/IGNITE-22638
> Project: Ignite
> Issue Type: Task
> Reporter: Pavel Pereslegin
> Priority: Major
>
> To perform catalog compaction, we need to determine and save a minimum time
> (low watermark) that guarantees that when next time we'll apply the raft log,
> we don't need the history up to that timestamp.
> To implement local calculation of the minimum timestamp, we need to provide
> an API with semantics similar to CheckpointListener#beforeCheckpointBegin (or
> afterCheckpointEnd, *to be clarified*) to save this timestamp.
> This timestamp make sence only for groups (*clarify*) with persistence, but
> it would be nice to have a common API (for example in MvPartitionStorage),
> and so the implementation requires collaboration with the storage engine
> team).
