Efficiently remove expired cache data in Laravel.
Situation
As of writing, several Laravel cache drivers do not have automatic removal of expired cached items:
file
database
Why is it a problem?
Using any of the above cache drivers without regularly removing the expired items (aka "key eviction" in Redis) can result in storage overload, especially when you are creating a lot of temporary items with random keys.
The cache:clear
command from Laravel works, but might not be the thing you want. It does not check item expiry (it removes everything), and also clears the Laravel framework cache (e.g. /bootstrap/cache/*
), which can be especially problematic when you are using the file
cache driver (consider a case: cache items are created by the www-data
user but /bootstrap/cache/*
is owned by the ubuntu
user).
In this case, this library can help you remove only the expired items in your cache. See below sections for more details.
This library is designed to be memory efficient and (for database
caches) non-blocking, so even if there are a lot of items in the cache (e.g. you are running this for the first time to deal with an oversized cache), it can still run reasonably well.
Install
via Composer:
Supported cache types
The following cache drivers from cache.php
are currently supported:
database
file
Some drivers (e.g. memcached
, redis
) will never be supported because they have their own item eviction mechanisms; use those features instead of this library!
Custom eviction strategies can be defined for other cache drivers that does not have their own eviction mechanisms (see FAQ section).
Usage
You may run this in the command line:
Or, you may put this into your console kernel schedule:
The relationship with cache.php
This library checks the cache name (not driver!) inside cache.php
to determine which cache to clear. This means, if you have the following cache.php
...
... and you run the command like this ...
... then, you will only evict the local_store
cache. The another_store
cache is unaffected by this command (assuming both are using separate directories, of course).
Testing
Using orchestra/testbench
(customized PHPUnit) via Composer:
Frequently-asked questions (FAQ)
How to define custom eviction strategies?
You can do so inside your Laravel service provider. Simply do the following:
Will this library help me reclaim database
disk spaces?
No, but if you are using this library regularly to evict expired items, then you do not need to worry about reclaiming free space. For more details, talk with a system admin/database specialist.
