DuckDB has released DuckLake v1.0, a production-ready lakehouse format that stores all metadata in a SQL database rather than scattered files. The format includes a stable specification, a reference implementation via DuckDB extension, and backward compatibility guarantees. This approach aims to improve metadata management and interoperability for data lakehouses.
Background
Lakehouse formats like Delta Lake and Apache Iceberg have emerged to bridge data lakes and data warehouses, but typically rely on file-based metadata storage. DuckLake introduces a novel approach using SQL databases for metadata management.
