Question for Mastodon Admins: are you using the `REDIS_NAMESPACE` configuration variable?
If yes, can you reply and explain why you are using it?

We will need to drop support for it, as Sidekiq no longer supports it, and I want to be certain we understand every usage to prepare a migration guide.

I'm using this variable now because I used to use one Redis database for multiple services

It's probably a bad idea to run multiple systems in the one Redis instance, especially if they use Redis Pub/Sub at all, to quote the documentation:

> Pub/Sub has no relation to the key space. [...] Publishing on db 10, will be heard by a subscriber on db 1.

Redis Pub/Sub

How to use pub/sub channels in Redis

(redis.io)

I'd strongly encourage migrating away from that as soon as you can.

I now have a separate Redis database in use, but the `REDIS_NAMESPACE` variable is still in use.

@Lafiel @admin @renchap

hmm, okay. Thanks for the update.

I would also like to figure out how to delete this variable when saving data.

@Lafiel @admin @renchap there is a script that could help, but there'd be some risks involved (we're trying to minimise those)
