Redis Cluster hashslots.

[Vineel Yalamarthi]

Hi there

I understand we can migrate hash-slot for one node to another. Can we also replicate specific hash-slot from one node to another.

Hello Vineel,

Replication in Redis is always at shard level (i.e., "node"), so replicas consist of the complete hash slots as their respective masters. As far as I know, there's no way to replicate only specific hash slots. May I ask why you are interested in this capability and the nature of the problem that you're trying to solve?

Cheers,

Itamar

If we have that capability, I thought we could write our implementation of a consistent-hash ring. So that we can move slots around in such a way every slot is replicated and all nodes are masters. Cluster resizing becomes very easy and we would have minimum slot movement.
