    $k = "hello";
    $v = "world";
    $cache->set($k, $v); //return true
    $cache->get($k); //world
    $cache->has($k); //true
    $cache->delete($k); //true
    $cache->get($k); //null
    $cache->has($k); //false
    
    /**

    */
    $region = "us-west-1";
    $tableName = "sandbox-demo-cache";
    $cache = new \RW\DynamoCache($tableName, [
        "region" => $region,
    ]);
