Guidance

Most subdirectories in docs/docs/guides correspond to phases in the data engineering lifecycle:

• Build: Creating data pipelines with core Dagster abstractions, particularly projects, assets, resources, and components.
• Automate: Automating data pipelines with declarative automation, schedules, and sensors.
• Operate: Managing pipeline operations with run configuration, environment variables and secrets, and concurrency.
• Log and debug: Understanding built-in structured event logs and raw compute logs, configuring custom loggers, capturing Python logs, and debugging assets during execution with pdb.
• Observe: Using alerts, the Dagster+ asset catalog, asset freshness policies, and Insights to observe data pipelines.
• Test: Testing assets and pipelines in Dagster to ensure data remains consistent and fresh.

The docs/docs/guides/labs subdirectory contains documentation of new features under active development. All pages in the Labs section should import the early access partial and reference it at the top of the page.

The docs/docs/partials subdirectory contains files with text that is referenced in multiple places throughout the documentation.

Examples

• docs/docs/guides/build/assets/asset-selection-syntax
• docs/docs/guides/automate/declarative-automation

docs/docs/integrations

Audiences

• Data pipeline builders

Guidance

• .mdx files are generated from .rst files in sphinx/sections/integrations and should not be directly edited. Instead, update the corresponding .rst file. Docstrings for classes and modules in corresponding files in python_modules/libraries may also need to be updated.
• If an integration has a component implementation, the component documentation should be placed in the index page of the integration subdirectory

Examples

• docs/docs/integrations/libraries/databricks
• docs/docs/integrations/libraries/fivetran

docs/docs/migration

Audiences

• Data pipeline builders
• Data platform owners

Guidance

• docs/docs/migration/upgrading.md is automatically populated by /MIGRATION.md through a custom React component. Do not edit upgrading.md directly.
