Choose solely publish id and meta worth with WP_Query

I am creating a easy rank plugin, which permits guests to love the posts and likewise exhibits the whole like scores for every tag within the plugin’s admin web page. I would like each publish IDs (with the intention to attain the tag information of them) and like values.

That is my question in the intervening time:

$args = array(
    'meta_key' => '_Like',
    'orderby' => 'meta_value',
);

$question = new WP_Query($args);

However this question returns the entire publish object, it isn’t environment friendly for the reminiscence. I solely want _Like worth and the post_id. Is there a greater question for this ?
