When editing cache mappings most of a Primary store and a Final store setting. These setting really need to be defined as to their purpose.
Redis Cache Store Instance
The Section 6 Adding cache store instances section of this doc has these four options:
6.1 File cache 6.2 Memcache 6.3 Memcached 6.4 MongoDB
What about Redis? Can a "Redis cache store instance" be used here too? If so, please expand the article to explain this.
Memcache / Memcached
As of May 2019 various documents indicate that Memcache and Memcached are old technologies that aren't fully compatible with PHP 7 anymore. Examples:
- MDL-55602 says "memcache is not PHP7 compatible".
- Re: memcached problem
- Re: Memcahed and moodle 3.5
- Upgrading 3.1.5 to 3.4.1
Should this Memcache / Memcached section be removed from this documentation, or at least updated to indicate the modern alternatives that should be used instead?
