Kolmos, the database that wants to explain itself

Field notes

Kolmos describes a storage pipeline built from a write-ahead log, background compaction, columnar content-addressed storage, and vectorized scans over Cloudflare R2. Its compatibility surface names PostgreSQL, MySQL, and MongoDB drivers, while the recovery design pins sandboxed WASM decoders in segment footers. The homepage cites FastCDC, Blake3, Apache DataFusion 54.1, and a 500 GB cost comparison, but the supplied evidence does not verify the advertised compression or savings benchmarks.
