Altertable

dbt

dbt (data build tool) helps data teams model and transform analytical data. Use the Altertable adapter to run dbt models directly in your Altertable lakehouse.

Installation

The Altertable adapter for dbt is available on PyPI and currently requires Python 3.10+ with dbt-core >=1.8,<2.0.

pip install dbt-altertable

If you manage Python dependencies with uv, you can install it with:

uv add dbt-altertable

Configuration

Add an Altertable profile to your profiles.yml file. By default, dbt looks for profiles in ~/.dbt/profiles.yml, but you can also place it in your project directory or specify a custom location using the --profiles-dir flag. Learn more about dbt profiles in the dbt documentation.

SQL Dialect

Altertable uses DuckDB as its query engine, so all SQL queries in your dbt models must use DuckDB-flavored SQL. This includes using DuckDB's functions, syntax, and data types.

Learn more about DuckDB SQL in the DuckDB documentation.
