-----------------------------------
Summary: Point-In-Time View
Key: HDDS-15188
URL: https://issues.apache.org/jira/browse/HDDS-15188
Project: Apache Ozone
Issue Type: Sub-task
Components: OM
Reporter: Chu Cheng Li
Assignee: Chu Cheng Li
Support to create ozone snapshot like point in time view on existing bucket,
then following operations like delete or update for the keys that are created
before the PIT View, we would store the preimage of those deleted/updated keys,
so the lookup to PIT View stay consistent.
Then we would build the bucket fork feature on top of this. fork = PIT View +
Fork Overlay.
I am thinking if this could replace the ozone snapshot feature if we figure how
to efficiently comparing the diff between two PIT View, the bucket
replication/event notification might also be able to build on top of PIT View.
