Warning: html_entity_decode(): charset `, such as posts in a WP_Query loop, it often makes * sense to prime various metadata caches at the beginning of the loop. This means fetching all * relevant metadata with a single database query, a technique that has the potential to improve * performance dramatically in some cases. * * In cases where the given metadata may not even be used in the loop, we can improve performance * even more by only priming the metadata cache for affected items the first time a piece of metadata * is requested - ie, by lazy-loading it. So, for example, comment meta may not be loaded into the * cache in the comments section of a post until the first time get_comment_meta() is called in the * context of the comment loop. * * WP uses the WP_Metadata_Lazyloader class to queue objects for metadata cache priming. The class * then detects the relevant get_*_meta() function call, and queries the metadata of all queued objects. * * Do not access this class directly.
