Use second cache flexibly in Laravel.

Installation

composer require hms5232/laravel-twin-cache

Usage

config

Add twin store in config/cache.php:

'stores' => [
    // other store config here

    'twin' => [
        'driver' => 'twin',
        'older' => env('TWIN_CACHE_OLDER', 'redis'),  // First/preferred cache
        'younger' => env('TWIN_CACHE_YOUNGER', 'database'),  // Second/backup cache
        'sync_ttl' => env('TWIN_CACHE_TTL'),  // TTL for younger synced to older. Default is null => forever
    ],
],

Change cache drive in .env:

CACHE_DRIVER=twin

method

All Laravel built-in methods modify the older cache, and you can add suffix Twin to method name for twin cache.

For example, you want to update both older and younger cache:

Cache::put('foo', 'bar');
// change "put" to "putTwin"
Cache::putTwin('foo', 'bar');

Another example, a key is in younger cache drive but doesn't exist in older. You want to sync this key when select this key:

// only select older cache
Cache::get('foo');

// This will select older cache first
// If no result, select younger, else return result
// 1. If exists in younger, insert into older cache and return
// 2. If it doesn't exist, return default value
Cache::getTwin('foo', 'bar');

So you can use second cache flexibly depend on need.
