This is really interesting, it's (basing it on SQLite) exactly what I was expecting CloudFlare to do for their first DB.
Its perfect for content type sites that want search and querying.
Anyone from CF here, is it using Litestream (https://litestream.io) for its replication or have you built your own replication system?
I assume this first version is somewhat limited on write performance having a single "main" instance and SQLite laking concurrent writes? It seems to me that using SQLite sessions[0] would be a good way to build an eventually consistent replication system for SQLite, would be perfect for an edge first sql database, maybe D2?
