Changelog

The first public release of Lakefront, an HTAP engine for TypeScript on Bun.

• open() an engine against a Postgres catalog and a data directory; boards are created on first write, with columns inferred or declared up front.
• Writes are durable at the Postgres commit through a group-committed write-ahead log, and are flushed into a DuckLake of Parquet files off the write path.
• Reads come from per-board DuckDB replicas, with read-your-write watermarks.
• watch() gives one change feed, identical embedded and over HTTP.
• serve(), route() and connect() run it as HTTP server nodes behind cache-affinity routing, with a typed client and capability tokens.

Requires Bun 1.2 or later. Docs: https://lakefront.folsomintelligence.com
