Caching with Redis on a Parse Server

I'm on a 2.6.3 Parse Server and I need to cache the results of queries, to speed things up!

I understand that Parse Server offers a Redis adapter. What exactly do I have to do, in order to start using Redis? Are there any modules I should install? Anything I should import or configure?

Also, I found this on Parse's documentation:

Those cache adapters can be cleaned at anytime internally, you should not use them to cache data and you should let parse-server manage their data lifecycle.

What do they mean by saying you should not use them to cache data and you should let parse-server manage their data lifecycle.? Should I not use the adapter?

What the doc is saying is that parse caches with it's own in-memory structure by default, but it leaves developers the option to use reddis as a substitute. To opt for that, just (1) setup redis as you typically would, (2) initialize the parse server with a RedisCacheAdapter that's been configured with your redis URL.

The point you're asking about: "you should not use them to cache data ..." means that Parse will continue to decide when to cache, when to retrieve from cache, and when to clean, etc. but it will do so by invoking the redis that you configured with.

I think the major advantage to this more elaborate setup is redis's distributed capability. If you're not running on a cluster, you may find the redis idea to be about equivalent performance-wise and a little messier setup-wise as not doing it.
