LiteFS Cloud: Distributed SQLite with Managed Backups
Man this is cool. While I really enjoy my own solution of using a custom SQLite vfs that stores your db transparently in dynamodb[0], this really is a compelling alternative.
I wonder how viable this would be to use from aws lambda? It seems like the way lambda does concurrency probably doesn't play all that well with litefs. Maybe it's time to move some workloads over to fly.io.

Ask HN: What could a modern database do that PostgreSQL and MySQL can't
There's a bunch of projects that have implemented this. I wrote a SQLite VFS in Go that lets you query a read-only SQLite db over http (including from s3) [0].
The VFS API offers the possibility for weirder storage solutions, if thats the type of thing you're into. Recently I've been moving some of my personal websites hosted on AWS Lambda over to use a read/write sqlite db backed by DynamoDB[1]. There are a bunch of limitations to this type of thing (like it uses a global write lock), but it works nicely for DBs that have low write frequency.

CursusDB – A new scalable distributed document oriented database
Seems like you could do the same with rqlite [1], since SQLite supports JSON.

Adding new database engine support
I found simple distributed RQlite https://github.com/rqlite/rqlite based on raft and sqlite. How hard is to add it?

So, you want to deploy on the edge?
rqlite[1] creator here, happy to answer any questions. rqlite also supports read-only nodes, which can also help with reads at the "edge". It probably wouldn't scale to 100s of nodes, it is an option.
"rqlite supports adding read-only nodes. You can use this feature to add read scalability to the cluster if you need a high volume of reads, or want to distribute copies of the data nearer to clients – but don’t want those nodes counted towards the quorum. These types of nodes are also known as non-voting nodes."
