Horizon: Excessive use of Redis databases

[tillkruss]

By default Horizon uses Redis databases 9, 10, 11, 12, 13, 14, 15 for jobs, supervisors, tags, metrics, locks, etc.

I'm sure it makes sense to avoid userland namespace conflicts, like job:{id}.

Can Horizon be configured to only use one or two databases? Are there any drawbacks to that? Maybe all Horizon keys could be prefixed with horizon:?

I'm asking because a lot of Redis hosting providers only supply a single database 0, some offer more in higher tiers, very few offer 16 out of the box.

Any chance you could link a few redis providers? Since redis itself offers 16 databases out of the box, i'd be surprised any provider didn't offer the same functionality

Even when hosting it myself I would like to contain Horizon to a single redis db tbh.

@alexbowers Redis Cluster does not support multiple databases like the stand alone version of Redis.

Ah, I was not aware. In that case, support

Right, that's a good point:

Redis Cluster does not support multiple databases like the stand alone version of Redis. There is just database 0 and the SELECT command is not allowed.

Taken care of, Horizon now ises a single database and a prefix.
