Write-only workloads:

Keep metadata locally to the node

Read-only workloads:

Check if metadata replicated on this node
If not, get metadata using distributed hashing and keep until space is needed

Read-After-Write File Per Process:

Keep metadata locally on node
Reads and writes are automatically synchronized.

Read-After-Write Across Processes (Strong Consistency):

The set of replicas need to be tracked
For each write, invalidate replicas
For each read, cache replica
