use Illuminate\Events\Dispatcher;
use Illuminate\Container\Container;
$capsule->setEventDispatcher(new Dispatcher(new Container));

$value = Cache::remember('users', $minutes, function() {
    return DB::table('users')->get();
});

protected static function boot()
{
    parent::boot();
    
    static::created(function ($model) {
        // cache model
    });
}
