hi,
I want to understand how are you guys planning to integrate
NSR volumes to the existing CLIs. Here are some thoughts I had, wanted
to know your thoughts:
At the heart of both the replication/ec schemes we have
1) synchronization mechanisms
a) afr,ec does it using locks
b) nsr does it using leader election
2) Metadata to figure out the healing/reconciliation aspects
a) afr,ec does it using xattrs
b) nsr does it using journals
I want to understand if there is a possibility of exposing these as
different modules that we can mix and match, using options. If the users
choose 1b, 2b it becomes nsr and 1a, 2a becomes afr/ec. In future if we
come up with better metadata journals/stores it should be easy to plug
them is what I'm thinking. The idea I have is based on the workload,
users should be able to decide which pair of synchronization/metadata
works best for them (Or we can also recommend based on our tests).
Wanted to seek your inputs.
Pranith
