#56272 closed enhancement (fixed)

REST API: Prime post caches in comments in endpoint.

Reported by: spacedmonkey's profile spacedmonkey Owned by: peterwilsoncc's profile peterwilsoncc
Milestone: 6.1 Priority: normal
Severity: normal Version: 4.7
Component: REST API Keywords: has-patch commit has-dev-note
Focuses: performance Cc:


In the WP_REST_Comments_Controller class, there are multiple calls to the comment's post, why calling get_post like this,

   $post = get_post( (int) $comment->comment_post_ID );

Post caches should be primed using the update_comment_post_cache param.

In 53772:

REST API: Prime post caches in comments endpoint.

Prevent each call to get_post() triggering a seperate database query by priming the cache of each comment's post in
the REST API's comments endpoint.

Props spacedmonkey, timothyblynjacobs.
Fixes #56272.

There are a lot of caching API related changes in 6.1 and a dev note should be written collecting them all. Marking this for inclusion.
