dbt-polars
A dbt adapter that runs models locally using Polars. Instead of connecting to a database, dbt-polars reads and writes files — on your local filesystem, Azure Blob Storage, AWS S3, or an Iceberg catalog.
Installation
pip install dbt-polars
Extra dependencies are required for cloud and Iceberg backends:
pip install 'dbt-polars[azure]' # Azure Blob Storage
pip install 'dbt-polars[s3]' # AWS S3
pip install 'dbt-polars[iceberg]' # Apache Iceberg (SQLite, REST, Databricks, …)
Catalogs
dbt-polars uses catalogs to define where data is stored. Each catalog maps to a storage backend. You can configure multiple catalogs in a single profile and reference them from your models.
| Catalog | Backend | Status |
|---|---|---|
local |
Local filesystem | Usable |
iceberg with SQLite |
Iceberg + SQLite metastore | Usable |
iceberg with REST + Databricks |
Iceberg REST API (Unity Catalog) | Experimental |
iceberg with other backends |
Any pyiceberg-supported backend | Experimental |
azure |
Azure Blob Storage / ADLS Gen2 | Experimental |
databricks |
Unity Catalog REST API + credential vending | Experimental |
