Unleash Edge with Redis Cluster issues

[issvvv]

Hey,

I have some questions and suggestions related to Redis integration:

1. Would it be possible to add a feature to specify a pattern for Redis keys via an environment variable? For example, something like edge_prod:*, so that all keys created by Unleash Edge would be prefixed consistently. This could help with key management and isolation.

2. I'm encountering an error when connecting Unleash Edge to a Redis Cluster:

Failed to load tokens from cache PersistenceError("Error connecting to Redis: It failed to check startup nodes. - IoError")

The documentation on Redis Cluster support seems a bit sparse and Debug/Trace mode doesn't help to resolve this problem. I'm not sure if I'm missing some configuration or if the Redis Cluster interaction is not fully implemented yet. Specifically, it's unclear whether I should specify a single host from the cluster or all masters. It doesn't even connects with default Redis user.

Could you please help with these points or point me to more detailed documentation?

Hi @issvvv can I ask you to please create an issue on https://github.com/Unleash/unleash-edge

1. This sounds like a feature request we'd be happy to implement, please, file an issue on the project itself
2. Agree that the cluster documentation could be better, our redis driver didn't have very good docs for this either. From https://docs.rs/redis/0.32.5/redis/cluster/index.html now, it seems like you should at least give all redis/valkey nodes. I also see that we don't support username and password as separate parameters when using cluster mode, it must be embedded in the URLs. I've made Redis persistence: Cluster mode - support username password as separate parameters unleash-edge#1139 to remember this.

Thanks, hope it helps on the next versions!

Honestly, I just thought about why I need a cluster at all, since I see that Edge only writes two keys to Redis and it doesn't really need to be sharded.. Or maybe my Unleash is not big enough so Redis contains only one key for features and one for tokens.

But yeah, adding the above features and some documentation would be cool! :)
