This task represents two streams of work:
- The longer-term work associated with reducing DiscussionTools' usage of the parser cache and
- The near-term work of modifying the parser cache expiry to reduce its usage so the Editing Team can proceed with scaling DiscussionTools features.
This section contains the in-progress plan for reducing DiscussionTools' usage of the parser cache.
