Redis prefix

[bencyoung]

Would it be possible to add an optional prefix to all of the keys in the Redis DB. We already store some other data in Redis, and if you're using clustering then you can only use DB 0, so it would be nice if they didn't overlap. It could be configurable so that it doesn't impact people who don't need it?

I'm not sure if that's really necessary. You can easily craft prefixed cache keys yourself ;)

[bencyoung]

That's true, although you'd need to know at the cache consumer side that:

1. You'd using Redis
2. There are other users of the same Redis DB

so it means the knowledge has to propagate. It's not a major concern, but more of a nice to have.

[MichaCo]

Yup I agree, would be nice to have.
I'll keep it in mind

I support this notion. Alternatively, or in addition, please add a similar option for prefixing regions.

I also support this, i really feel this feature is missing.

Microsoft.Extensions.Caching.Redis already have a feature like this using InstanceName

services.AddDistributedRedisCache(options =>
{
    options.Configuration = "ConnectionString";
    options.InstanceName = "CacheKeyPrefix";
});

We run multiple applications on the same Redis instance and use prefixes to seperate applications. It gets really hard to enforce these key prefixes throughout an application without a feature like this.
