Summary: Support bucket forks
Key: HDDS-15120
URL: https://issues.apache.org/jira/browse/HDDS-15120
Project: Apache Ozone
Issue Type: New Feature
Reporter: Ivan Andika
Currently, Ozone supports bucket snapshot which creates a read-only immutable
state of the entire bucket for use cases such as backup, replication,
compliance, etc.
However, in the recent rise agentic workloads, there is a need for systems to
implement forking / branching to cater for multi-agents workload. The idea of
forking and branch is similar to Git branch / worktrees where a new "branch" is
created based on the base directory. Multiple agents can fork the same base
file system in parallel and mutate these forks without affecting each other.
These forks should also have zero-copy, similar to snapshot. Additionally,
these forks lifetime can varies (it can be retained for a long time or
discarded quite quickly).
Example systems
* NeonDB branching: https://neon.com/docs/introduction/branching
* Tigris Object Store: https://www.tigrisdata.com/docs/snapshots-and-forks/
(please see the related blogs on the implementations for the idea).
Ozone can consider supporting this feature. With the rise of the storage
compute separation architecture on databases (OLAP or OLTP), the compute /
caching layer can rely on Ozone as the backing store for agentic workloads
since Ozone supports snapshot and forking. Ozone then can position itself as
the object store for agentic workloads.
This ticket acts as a way to start a discussion on this direction.
