    Cache::redis()->keys('*')
);

Cache::redisPush("something", [ 1 => 2, 3 => "b"]);
Cache::redis()->push("something_2", [ 1 => 2, 3 => "b"]);

Правило типа 'callback' может быть:

• Class@method
• Class::method
• customFunction
• instance of Closure

Параметры передаются всегда массивом.

TODO

• нужен ли кастомный декодер json?
