README
Feather - a highly performant SQLite Cache Driver for Kirby 3
Installation
- unzip master.zip as folder
site/plugins/kirby3-sqlite-cachedriver
or git submodule add https://github.com/bnomei/kirby3-sqlite-cachedriver.git site/plugins/kirby3-sqlite-cachedriver
orcomposer require bnomei/kirby3-sqlite-cachedriver
Why
Memcached < File < Redis < SQLite < APCu
Kirby ships with built in support for File, Memcached and APCu Cache Drivers. I created a Redis Cache Driver which is imho best suited for larger caches. If your hosting does not support Memcached, APCu or Redis then your next best choice is this SQLite Cache Driver.
2 is enough and about 35% faster
Let's imaging this typical scenario: During a single pageview you need to access, 100 cached values. Some of them already exist, some not, some need to be refreshed and yet others need to be deleted. With a File Cache this would cause at least 100 filesystem operations in total. Using this SQLite Cache you will have only 1 file read and maybe 1 file write per pageview no matter how many values you get, update or remove. ✌️ But reading and writing data to SQLite is not instantaneous, so it will be at least 35% faster.
Usage
Cache methods
$cache = \Bnomei\SQLiteCache::singleton(); // or $cache = feather(); $cache->set('key', 'value', $expireInMinutes); $value = feather()->get('key', $default); feather()->remove('key'); feather()->flush();
Benchmark
feather()->benchmark(1000);
sqlite : 0.075334072113037 file : 0.11837792396545
ATTENTION: This will create and remove a lot of cache files and sqlite entries
No cache when debugging
When Kirbys global debug config is set to true
the complete plugin cache will be flushed and no caches will be read. But entries will be created. This will make you live easier – trust me.
How to use Feather with Lapse or Boost
You need to set the cache driver for the lapse plugin to sqlite
.
site/config/config.php
<?php return [ 'bnomei.lapse.cache' => ['type' => 'sqlite'], 'bnomei.boost.cache' => ['type' => 'sqlite'], //... other options ];
Setup Content-File Cache
Use Kirby 3 Boost to setup a cache for content files.
Pragmas
The plugin comes with aggressive defaults for SQLite Pragmas to optimize for performance. You can change these in the settings if you need to.
