We host applications that do sharding like this, but when we build our own stuff at Fly.io, or publish tooling like LiteFS, we're generally not thinking about sharding right now. We like things that are easy to keep our heads around.
We're a hosting provider, not really a database provider. Systems that do sharding, Raft consistency, and stuff like that are built on top of systems like ours, not so much inside of them. :)
Gotcha, that makes sense; I'm probably thinking of Cloudflare Workers, then. It might've come up from kentonv's comments in the recent post about Cap'n Proto 1.0.
Hmm, not in that thread, but maybe in a thread about D1 or Durable Objects? We are indeed trying to make it as easy as possible for applications to shard databases by user or by "document".
