- Replace all the DB slaves in codfw (need new hardware to support traffic)
- Update and/or replace GTID_Wait / heartbeat
- Decide where to move mainstash data (non-session data in Redis)
- Migrate mainstash data to new location
- Decide what is the acceptable replication lag for MediaWiki?
- Current lag is 10-15 seconds. ~1 second would be acceptable for 90% of reads get what they need, last 10% needs reengineering
- Evaluate lag for codfw, if not acceptable, then engineer a solution
- Update MediaWiki code to wait for replication (if needed)
- TLS Proxy work
- Separate traffic on varnish level
- Serve thumbnails
