Redis based Cache-Driver

Installation

• unzip master.zip as folder site/plugins/kirby3-redis-cachedriver or
• git submodule add https://github.com/bnomei/kirby3-redis-cachedriver.git site/plugins/kirby3-redis-cachedriver or
• composer require bnomei/kirby3-redis-cachedriver

Why Redis?

Memcached and APCu have more restrictive defaults. Redis does not have these limitations and is by very fast with proper configuration.

Setup Cache

Set your Kirby Cache-Driver to redis for Plugin caches or in your site/config/config.php. All redis related params can be callbacks. You might even load values from an .env File.

site/config/config.php

return [
   'bnomei.boost.cache' => [
       'type' => 'redis',
       'host' => function() { return env('REDIS_HOST'); },
       'port' => function() { return env('REDIS_PORT'); },
       // 'database' => function() { return env('REDIS_DATABASE'); },
       // 'password' => function() { return env('REDIS_PASSWORD'); },
   ],
];

Cache methods

$redis = \Bnomei\Redis::singleton();
$redis->set('key', 'value', $expireInMinutes);
$value = $redis->get('key', $default);
$redis->remove('key');
$redis->flush(); // data in memory
$redis->flushdb(); // DANGER: flushes full redis db!!!

Predis Client

$redis = new \Bnomei\Redis($options, $optionsClient);
$client = $redis->redisClient();
$dbsize = $client->dbsize(); // https://bit.ly/2Z8YKyN

Benchmark

$redis = new \Bnomei\Redis($options, $optionsClient);
$redis->benchmark(1000);

redis : 0.29747581481934
file : 0.24331998825073

ATTENTION: This will create and remove a lot of cache files and entries on redis

No cache when debugging

When Kirbys global debug config is set to true no caches will be read. But entries will be created. This will make you live easier – trust me.

How to use Redis Cache Driver with Lapse or Boost

You need to set the cache driver for the lapse plugin to redis.

site/config/config.php

<?php
return [
    'bnomei.lapse.cache' => ['type' => 'redis'],
    'bnomei.boost.cache' => ['type' => 'redis'],
    //... other options
];

Setup Content-File Cache

Use Kirby Boost to setup a cache for content files.
