`WP_Comment_Query` now fetches comments in two stages: (1) a query to get the IDs of comments matching the query vars, and (2) a query to populate the objects corresponding to the matched IDs. The two queries are cached separately, so that sites with persistent object caches will continue to have complete cache coverage for normal comment queries. Splitting the query allows our cache strategy to be more modest and precise, as full comment data is only stored once per comment. It also makes it possible to introduce logic for paginated threading, which is necessary to address certain performance problems. See #8071. data is only stored once per comment, instead of along with Built from https://develop.svn.wordpress.org/trunk@34310 git-svn-id: http://core.svn.wordpress.org/trunk@34274 1a063a9b-81f0-0310-95a4-ce76da25c4cd
