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.

Codebases to read
I'm partial to how cleanly written https://github.com/google/leveldb is. It is a reasonable size to fully read & grok in not too long.

Marmot: Multi-writer distributed SQLite based on NATS
If you're interested in this, here are some related projects that all take slightly different approaches:
- LiteSync directly competes with Marmot and supports DDL sync, but is closed source commercial (similar to SQLite EE): https://litesync.io
- dqlite is Canonical's distributed SQLite that depends on c-raft and kernel-level async I/O: https://dqlite.io
- cr-sqlite is a Rust-based loadable extension that adds CRDT changeset generation and reconciliation to SQLite: https://github.com/vlcn-io/cr-sqlite
Slightly related but not really (no multi writer, no C-level SQLite API or other restrictions):
- comdb2 (Bloombergs multi-homed RDMS using SQLite as the frontend)
- rqlite: RDMS with HTTP API and SQLite as the storage engine, used for replication and strong consistency (does not scale writes)
- litestream/LiteFS: disaster recovery replication
- liteserver: active read-only replication (predecessor of LiteSync)

9 years of open-source database development: reviewing the designs
Anyone knows how the DB this is about, https://rqlite.io/, compares with https://dqlite.io/ by Canonical (both seem to be distributed versions of sqlite)?

Transcending Posix: The End of an Era?
For folks' context, the new tool that's being discussed in the thread mentioned by the parent here is litefs [0], as well as which you can also look at rqlite [1] and dqlite [2], which all provide different trade-offs (e.g. rqlite is 'more strongly consistent' than litefs).

SQLite is not a toy database
I presume you're familiar with https://github.com/canonical/dqlite (made by my employer) and https://github.com/rqlite/rqlite (unrelated)? How will mvsqlite compare to those?

GitDB, a distributed embeddable database on top of Git
Check out dqlite, it's sqlite but with a raft consensus to distribute changes through a log: https://dqlite.io/ You can link it in as a library too, it sounds like exactly what you want.
- Ask HN: Free and open source distributed database written in C++ or C
What are some alternatives?
RocksDB - A library that provides an embeddable, persistent key-value store for fast storage.
rqlite - The lightweight, distributed relational database built on SQLite.
MongoDB - The MongoDB Database
kine - Run Kubernetes on MySQL, Postgres, sqlite, dqlite, not etcd.
Redis - Redis is an in-memory database that persists on disk. The data model is key-value, but many different kind of values are supported: Strings, Lists, Sets, Sorted Sets, Hashes, Streams, HyperLogLogs, Bitmaps.
better-sqlite3 - The fastest and simplest library for SQLite3 in Node.js.
SQLite - Unofficial git mirror of SQLite sources (see link for build instructions)
litestream - Streaming replication for SQLite.
