update_{$meta_type}_metadata_cache WordPress Filter Hook
The update_{$meta_type}_metadata_cache hook is called when the metadata cache for a given meta type is updated. This hook gives you the opportunity to update your own cached data in response to changes in the metadata cache. For example, you might use this hook to invalidate your cached data when the post_modified timestamp changes.
apply_filters( "update_{$meta_type}_metadata_cache", mixed $check , int[] $object_ids ) #
Short-circuits updating the metadata cache of a specific type.
Description
The dynamic portion of the hook name, $meta_type, refers to the meta object type (post, comment, term, user, or any other type with an associated meta table). Returning a non-null value will effectively short-circuit the function.
Possible hook names include:

Parameters
- $check
(mixed)Whether to allow updating the meta cache of the given type.
