Laravel Tagged Cache

Force a certain tag on your cache.

Why would I need this?

If you use the same Memcache server for multiple projects/tenants, it might be difficult to flush the cache for only one of them. The only options is to flush the entire cache. Using Laravel's built in TaggableStore, it's possible to flush the cache for only one project/tenant.

How does it work?

The tagged cache driver is a simple wrapper for another cache driver. All regular access to cache keys, such as get, put and remember, are forced to use the tags method and include the specified tag. Other special methods, such as lock are passed through without modification.

Installation

To get started with Laravel Tagged Cache, use Composer to add the package to your project's dependencies:

composer require paneidos/laravel-tagged-cache

Config

Specify a tagged store in your config/cache.php:

return [
    'stores' => [
        'memcache-tagged' => [
            'driver' => 'tagged',
            'backend' => 'memcache',
            'tag' => 'project_name',
        ],
        'memcache' => [
            // ...
        ],
        // ...
    ],
];

Example: replace your default store

return [
    'default' => 'tagged',
    
    'stores' => [
        'tagged' => [
            'driver' => 'tagged',
            'backend' => env('CACHE_DRIVER', 'array'),
            // Use the database name as the forced tag
            'tag' => env('DB_DATABASE', 'none'),
        ],
        // ...
    ],
];

Compatibility

Currently works with Laravel 5.6 and higher. The backend can be any store with support for tags. Note: the file store does not support tags.
