Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

FoundationDB: A Distributed Key-Value Store
When I was writing a Haskell client library for Hyperdex, another distributed kv store, I found it incredibly helpful to implement a simulator for correctness. This helped me identify which behavior was unspecified (arithmetic overflow: should error) or where my simulator deviated.

Alas, I think Hyperdex development paused a few years later. It's a shame that it stopped then.

FoundationDB: A Distributed Key-Value Store
I’ve been using FDB for toy projects for a while. It’s truly rock solid. That being said, I wish there were more layers.
Ideally someone could implement the firestore or dynamodb api on top.

Go bindings to SQLite using Wazero
For the rough plan, it's Cloud Backed SQLite meets FoundationDB.

SQLite-based databases on the Postgres protocol? Yes we can
- Oh, and if you're wondering about backup to S3, they have that too: https://github.com/libsql/bottomless
- Uh, sqld can integrated with this https://github.com/losfair/mvsqlite, so now your SQLite is backed by FoundationDB!?
- Meanwhile Litestream exists https://github.com/benbjohnson/litestream/
- We Built Fly Postgres
-
Litestream doesn't do SQLite replication anymore (LiteFS does)
Shameless plug of my [mvSQLite](https://github.com/losfair/mvsqlite) project here! It's basically another distributed SQLite, but with support for everything expected from a proper distributed database: synchronous replication, strictly serializable transactions, + scalable reads and writes w/ multiple concurrent writers.

SQLite: QEMU All over Again?
This project looks really exciting!
I'm working on mvsqlite [1], a distributed SQLite based on FoundationDB. When doing the VFS integration I have always wanted to patch SQLite itself, but didn't because of uncertainty around correctness of the patched version...
A few features on my wishlist:
1. Asynchronous I/O. mvsqlite is currently doing its own prefetch prediction that is not very accurate. I assume higher layers in SQLite have more information that can help with better prediction.
2. Custom page allocator. SQLite internally uses a linked list to manage database pages - this causes contention on any two transactions that both allocate or free pages.
3. Random ROWID, without the `max(int64)` row trick. Sequentially increasing ROWIDs is a primary source of contention, and causes significant INSERT slowdown in my benchmark [2].

Show HN: Query SQLite files stored in S3
That DynamoDB VFS looks cool! I agree that the VFS api makes one think about plenty of crazy ideas. Someone is working on a VFS based on Foundation DB[0] that looks very promising. It was recently discussed here[1]
