Cache Driver

You can choose your cache driver depending on your scenario

Type Scenarios Shareable Effect Description
array Temporary, Debug X Cache on single request Only store the cache data in the array variable and the cache will DISAPPEAR after the whole request
file Always available V (Single Server) Cache on single file Store the cache data in the file. The same server can share the same cache data, but it COULD NOT share the cache data from the different servers
database Always available O Cache on SQL database table Store the cache data in the SQL database table, and it COULD share the cache data from the different servers
redis Dedicated O Cache on NoSQL redis database Store the cache data in the NoSQL redis database, and it COULD share the cache data from the different servers
memcached Dedicated O Cache on NoSQL memcached database Store the cache data in the NoSQL memcached database, and it COULD share the cache data from the different servers
dynamodb Dedicated O Cache on NoSQL dynamodb database Store the cache data in the NoSQL dynamodb database, and it COULD share the cache data from the different servers

Database Cache Driver

Cache table

Schema::create('cache', function ($table) {
    $table->string('key')->unique();
    $table->text('value');
    $table->integer('expiration');
});
