dbt v2 ships with a built-in DuckDB adapter

duckdb.org by Geertjan Wielenga 7 min read Editor score 7/10

The Rust-based dbt Fusion engine ships with a built-in DuckDB adapter, alongside support for DuckLake and Iceberg catalogs and queries over dbt’s Parquet metadata. Data teams can evaluate a simpler DuckDB-based dbt setup and migration path.

What: dbt v2 is the first release with a built-in DuckDB adapter, running on the Rust-based Fusion engine.
How: Adapters in v2 connect through ADBC drivers; dbt downloads and caches the DuckDB driver on first run.
Why it matters: Built-in DuckDB support removes separate adapter installation for local dbt projects, while v2 adds DuckLake and Iceberg catalog support.
