May cause anachronisms in incoming events due to modifications in timestamp measuring, and consequently the write logic (if a bug exists causing miscalculation of incoming times). Should not impact previous events (relatively safe in that regard, I hope).

Adds a column family (index) to the DB and an admin command to index an individual room's messages by timestamp.
The column can be dropped, but is harmless either way.
You cannot necessarily undo the indexing, however.

Having admins manually request per-room indexing avoids the potentially massive overhead of a one-time startup migration.
The algorithm should be safe enough to not cause CPU spikes, even against non-indexed rooms.

Suggested improvements or additional test cases are always welcome.
