Using valkey instead of redis

[lyderic]

What would you like to be added:

I would like to have support for valkey (redis clone).

Why is this needed:

I am running my stack on Arch linux, where redis has been replaced by valkey in the default repository.

Many thanks for looking into this :-)

Also: thanks for juicefs, this is a fantastic piece of software!

Valkey should be supported out of the box as Valkey is a fork of Redis OSS v7.2.4.

Sorry, my feature request was misleading: valkey is indeed a drop-in replacement for redis. However, it doesn't show up in the documentation as a redis compatible database.

IMHO it would be a good idea to add it, as was done for KeyDB (another fork of redis), especially for Arch linux users as it is the default for this distro.

I think Valkey can be used directly without any additional explanation. If you have deeper insights into Valkey—such as its new features or performance improvements compared to Redis—a PR to add those details to the documentation is welcome.

I don't have any insights into Valkey, I'm afraid. So far, I use it as a replacement for Redis when needed. The URL redis://xxx works as per documentation.

Thanks.
