dbt-polars
dbt-polars integrates the flexibility and performance of Polars with the data governance and lineage capabilities of dbt.
Key features of dbt-polars:
- Run anywhere: Polars runs on any compute platform, so you’re not locked into an expensive data warehouse.
- Flexible: Available catalogs let you connect to local storage, Iceberg catalogs, Databricks, and more.
- Extensible: Create a custom catalog to fit your unique storage and warehouse needs.
- First-class Python models: Run Python models with the same performance and capabilities as SQL models.
- Mix Python and SQL: Choose the language that best fits the transformation.
- dbt-native: Bring lineage, documentation, and data testing into your workflow.
- Ingestion: Build efficient, incremental API ingestion with Python models and keep the entire pipeline visible in the lineage graph.
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[databricks]' # Azure Blob Storage
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 |
