Sigma (dagster-sigma)
Dagster allows you to represent the workbooks and datasets in your Sigma project as assets alongside other technologies including dbt and Sling. This allows you to visualize relationships between your Sigma assets and their dependencies.

Sigma API
Here, we provide interfaces to manage Sigma projects using the Sigma API.
Assets (Sigma API)
- class dagster_sigma.SigmaOrganization
Represents a workspace in Sigma and provides utilities to interact with the Sigma API.
- build_defs
- deprecated
This API will be removed in version 1.9.0. Use dagster_sigma.load_sigma_asset_specs instead.
Returns a Definitions object representing the Sigma content in the organization.
Parameters: dagster_sigma_translator (Type[DagsterSigmaTranslator]) – The translator to use to convert Sigma content into AssetSpecs. Defaults to DagsterSigmaTranslator.Returns: The set of assets representing the Sigma content in the organization.Return type: Definitions
- class dagster_sigma.SigmaBaseUrl
Enumeration of Sigma API base URLs for different cloud providers.

- class dagster_sigma.DagsterSigmaTranslator
Translator class which converts raw response data from the Sigma API into AssetSpecs. Subclass this class to provide custom translation logic.
- class dagster_sigma.SigmaDataset
Represents a Sigma dataset, a centralized data definition which can contain aggregations or other manipulations.
- class dagster_sigma.SigmaWorkbook
Represents a Sigma workbook, a collection of visualizations and queries for data exploration and analysis.
- class dagster_sigma.SigmaFilter
Filters the set of Sigma objects to fetch.
Parameters:
- workbook_folders (Optional[Sequence[Sequence[str]]]) – A list of folder paths to fetch workbooks from.
- workbooks (Optional[Sequence[Sequence[str]]]) – A list of fully qualified workbook paths to fetch.
- include_unused_datasets (bool) – Whether to include datasets that are not used in any workbooks.
- dagster_sigma.load_sigma_asset_specs
- experimental
This API may break in future versions, even between dot releases.
Returns a list of AssetSpecs representing the Sigma content in the organization.
Parameters:
- organization (SigmaOrganization) – The Sigma organization to fetch assets from.
- dagster_sigma_translator (Optional[Union[DagsterSigmaTranslator, Type[DagsterSigmaTranslatorr]]]) – The translator to use to convert Sigma content into
dagster.AssetSpec
. - sigma_filter (Optional[SigmaFilter]) – Filters the set of Sigma objects to fetch.
- fetch_column_data (bool) – Whether to fetch column data for datasets, which can be slow.
- fetch_lineage_data (bool) – Whether to fetch any lineage data for workbooks and datasets.
- snapshot_path (Optional[Union[str, Path]]) – Path to a snapshot file to load Sigma data from,
Returns: The set of assets representing the Sigma content in the organization.Return type: List[AssetSpec]
