Review Comment:
@SteNicholas , Yeah it can be invoked but i see few problems with it
What if underlying file system is down and **updateMetadata** fails to sync
metadata, then there is no mechanism to bring it in sync with latest committed
metadata, and archival will remove replace commit eventually and it will end up
in an inconsistent state.
On the other hand in **archival process , it will be eventually in sync with
committed metadata** before replace commit getting archived.
I think consistent hashing metadata has strong dependency on archival
process, As it is dependent on active timeline replaced commit to load metadata.
