Stop pregenerating /page/metadata
Closed, ResolvedPublic

Description

We have moved all of the content that was originally served by /page/metadata into wikimedia-page-library or direct MediaWiki API requests by the client. Please stop storage and pregeneration of /page/metadata, as clients will not be using it, and we intend to remove it.

Pre-generation has been removed from change propagation, RESTBase is now querying PCS directly and the tables have been removed from storage. We are done here.
