Short, systems-oriented writing on durable memory, versioning, and reproducible search.
- Stratum: SQL that branches →
How we built a SIMD-accelerated columnar SQL engine on the JVM with copy-on-write branching - faster than DuckDB on 35 of 46 queries via the Java Vector API.
- Why We Built Datahike →
A personal story about functional values, long-lived systems, and the memory layer AI needs.
- Yggdrasil - Branching Protocols →
A protocol stack that brings Git-like branching to any storage system.
- The Git Model for Databases →
Copy-on-write, structural sharing, and branching - applied to your data.
- Why Search Needs Versioning →
Immutable search indexes for reproducible retrieval and systems that can explain themselves.
