Detailed Description

Job to update link tables for pages.

This job comes in a few variants:

• a) Recursive jobs to update links for backlink pages for a given title. These jobs have (recursive:true,table: set.
• b) Jobs to update links for a set of pages (the job title is ignored). These jobs have (pages:(<page ID>:(<namespace>,<title>),...) set.
• c) Jobs to update links for a single page (the job title) These jobs need no extra fields set.
