File Cache Storage
This cache adapter will store all of your data into files somewhere on the server's filesystem. Every key you store
represents one file on filesystem. If you have a lot of files, then you should sometimes run Cache::deleteOld() method.
To reduce wait time on file system and improve performance, storing values to file cache storage won't create or write
to filesystem in the moment you call Cache::set(). Instead, it'll be stored in memory and value will be written to
file when request (or) CLI script is done with execution.
Beware that framework will not delete files with expired values automatically. You are responsible for cleaning up old
files using Cache::deleteOld() method. Old files will be deleted only in one case - if you call Cache::has() on
the key that is old enough so framework sees the old file. Otherwise, nothing will happen.
Configuration
'some-key-name' => [
'enabled' => true,
'adapter_class' => '\Koldy\Cache\Adapter\Files',
'options' => [
'path' => null,
'default_duration' => 3600
]
]Options
Path
If path is defined, then all files will be stored to the path mentioned here. If null, all files will be stored to
log folder in storage (storage/log).
Default Duration
Every time when you call Cache::add() or Cache::set() methods, you can pass your custom duration on how long the
value is valid. If you don't pass duration, default_duration will be used. If default_duration is not set, then
3600 is used, which equals one hour.
Beware that file cache storage is not recommended on systems with high traffic. If you're using SSD storage on your server, writing and reading from filesystem will be fast, but it'll reduce the life your SSD.
