Two apps share one Redis. How to prevent cache collisions?

Question

Two different versions of the application (debug and release) share same instance of Redis. Both Debug and Release have identical source code and therefore identical caching keys for being stored in Redis.

Thus when Debug does redis.StringSet(key1, value1) Release could easily overwrite key1 or read incorrect value (since it should have its own key1).

Is there a way to avoid such interference?

Answer 1

Do not do that - sharing is bad. Spin a Redis instance per environment, each server has negligible overhead.
