Re: ORDER BY / GROYP BY slow - MySQL 8.0

With help from Xgc from #mysql the issue is resolved using indexes:

CREATE INDEX xxx1 ON wpks_posts (ID, post_type, post_status, post_date);
CREATE INDEX xxx2 ON wpks_term_relationships (object_id, term_taxonomy_id);
CREATE INDEX xxx3 ON wpks_postmeta (post_id, meta_key(20), meta_value(20));

Now these queries take 0.12 sec.
