Review Comment:
Couple of reasons for this:
- One is if there is no active consumption in a partition but you enable
snapshotting then we never get to snapshot the previous segments after server
restarts. Related issue -
https://github.com/apache/pinot/issues/12703#issuecomment-2154850044
- Other is now when we do a restart / rollout in a cluster, it becomes a one
commit cycle waiting time for us to have any segments compacted. The scale of
deletion is pretty huge (~600M records per day) and so imo it's a good
optimisation to have for making compaction work early.
