Does chihaya not support redis cluster mode？ about chihaya HOT 2 OPEN

Hmm, I've never used redis cluster mode. From reading the docs, this looks suspicious:

Redis Cluster supports multiple key operations as long as all of the keys involved in a single command execution (or whole transaction, or Lua script execution) belong to the same hash slot.

We use MULTI ... EXEC transactions for consistency. We didn't take hash slots into account (didn't even know those existed tbh), so I wouldn't be surprised if that breaks.

From the way we structure our data in Redis, I don't think it's straightforward to guarantee that keys used in one transaction are in the same hash slot. Maybe someone with more experience in Redis can figure this out at some point... sorry!

EDIT: About the specific error you're seeing: That looks like a redirect, which I also didn't know existed. I'd hoped our redis library/connector/whatever handled that, but maybe it doesn't (by default?). Also something to investigate.

Hello.

First at all, to use cluster, client must be support cluster, but chihaya uses library which does not. So, chihaya should use one of solutions, mentioned in provided issue.

If you need cluster for HA, well... it is not the best solution, because it not guarantees data consistency and potentially may lose data if node without replica dies. For HA sentinel (which redigo also does not support) is better solution, but it a little bit complex. If it applicable, you can use keydb fork of redis in multi-master (which also known as 'active-active') or active replica mode with (or without) some proxy if front of nodes (i.e. haproxy).
