definitions

Entry point for programmatically loading Dagster definitions for the project.

Dagster's component-based loader expects a function decorated with @dagster.components.definitions that returns the Definitions object to expose. This module provides that hook and centralizes the logic that discovers assets, resources, and schedules declared under :mod:data_platform.defs.

data_science()

Construct Dagster definitions from the data_science/defs module.

Returns:

Type	Description
Definitions	dagster.Definitions: A Definitions instance containing every asset, resource, sensor, and schedule discovered under the defs folder relative to the project root. The loader mirrors Dagster's CLI defs semantics so end users receive the same set of assets whether they invoke the CLI or the Python API.
