Changeset 53482 for trunk/src/wp-includes/pluggable.php

Timestamp:

Message:

Prime users cache in WP_Query and post REST API controller.

For a call to WP_Query or a post REST API request that contains posts from multiple authors, call the cache_users function, to ensure that all user data for post authors is primed in
a single database query. This results in far fewer database queries on multiple author sites.

Props spacedmonkey, timothyblynjacobs, peterwilsoncc.
Fixes #55716.
