Ref: https://github.com/streamnative/oxia/pull/622
### Motivation During the test, we found a cluster shards leader distribution like the image as follows. That is not good for distributed systems to rebalance traffic.
### Motivation Currently, we do not support shard splits for horizontal scaling. We should support it to allow for better dynamic scaling of clusters.
``` │ panic: runtime error: invalid memory address or nil pointer dereference │ │ [signal SIGSEGV: segmentation violation code=0x1 addr=0x40 pc=0x1a69d05] │ │ │ │ goroutine 134600539 [running]: │ │...
How can a consistent backup of Oxia be created for DR purposes? What is the procedure to restore from such a backup?
### Motivation In the current implementation. We don't support multi-AZ awareness. We can only create three nodes and give three replicas per shard, which will auto-distribute in the different AZs....
