DuckDB adds DuckLake extension for SQL-based lakehouse storage

DuckDB released a DuckLake extension, enabling DuckDB to read and write an open lakehouse table format that stores metadata in a catalog database and data as Parquet files. Users can install it via INSTALL ducklake, attach a DuckLake database with standard ATTACH syntax, and then create, query and modify tables using regular SQL, including updates, time travel queries, and schema evolution.
