Draft / placeholder:
## 1) Continue REST API build-out and service development mentoring
- Focus on high-traffic end points.
- Thumb API?
## 2) Migrate several job queue use cases to the change propagation service; start dependency tracking
- Build on work done in Q2 to replace job queue use cases.
- Support dependency tracking (by integrating with link tables, tracking new dependencies), and start using this for change propagation.
## 3) Storage: Separate hot from warm content; import full wikitext history
- Store current versions separately, so that they are cheaper to access & can be replicated to PoPs with modest resources.
- Improve compression ratios for old revisions, possibly at the cost of some access latency.
- Import the full wikitext history & evaluate this as an option for a longer-term ExternalStore replacement.
