Support for Redis v7 and newer

[4n4nd]

Hey team 👋 I was trying to upgrade my cluster from Redis version 6.2.x to 7.0.x. But it seems like v7 is not supported by the operator yet. This is the error that I get:

E0817 14:03:24.673063       1 redisnode.go:247] readiness check failed, err:Readiness failed, cluster slots response err: response returned from Conn: unmarshaling message off Conn: cannot decode resp array into string

Do we have any plans on supporting Redis v7?

Thanks!

We currently don't have any use cases that require 7.x, so we haven't looked into it yet. I'm not sure how much effort it will take to support both 6.x and 7.x, but it's definitely something we should look into as there are some nice features in the new version. The only problem is that we have a lot of other issues on our plate at the moment and won't be able to dedicate time to this in the near term. This is something we can try to get in our Q4 agenda.

Hello, team.

Do you have any updates about this issue?
We need support redis v7 in operator.

I don't have an update on this issue. It looks like someone submitted a PR for it, but I think there's going to be more to it than simply changing the version. This repo is also not being actively maintained at the moment. I'm currently maintaining a fork here. I hope to get changes merged back here periodically. I'll gladly accept a PR for this too :)
