Craft CMS memcached enabler

This yii-extension is a memcached drop in replacement for sessions, cache and mutex. The file Session handler and the file Cache driver are getting replaced to work with Memcache without the need for further configuration for Pro Apps hosted on fortrabbit., _(*1)

Requirements

Craft CMS (Version 3, 4, 5)
A Professional App on fortrabbit (see below for other hosting providers)

Install

Install the extension with Composer composer require fortrabbit/yii-memcached
Deploy the composer.json and composer.lock file with Git
That's it

Non-fortrabbit environments

Provide the following ENV vars, if your application is not running on fortrabbit:, _(*2)

MEMCACHE_COUNT (int, number of Memcached servers)
MEMCACHE_HOST1 (host name of first Memcached server)
MEMCACHE_PORT1 (port of first Memcached server)
MEMCACHE_HOST(n) (host name of nth Memcached server)
MEMCACHE_PORT(n) (port of nth Memcached server)

Good to know

Read the fortrabbit Memcache help why this is mandatory in multi node environments
This is not a Craft CMS plugin but an extension for the underlying Yii framework
This is not required for Universal Apps hosted on fortrabbit, since there is no Memcache and the file system is persistent
