Talk:Caching

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 is old technology that isn'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?
