When to use the ETL Data Pipeline template
An ETL pipeline from raw sources to dashboards: Extract pulls from APIs, databases, and files into Raw Storage, Validate Schema gates the load (with Quality Alerts branching off on failure), Transform and Join produce the curated layer in the Data Warehouse, and Metric Models feed the Dashboard.
- •Documenting a data platform so analysts know where numbers come from and where quality checks live.
- •Onboarding data engineers to the ingestion stages and the failure path that fires quality alerts.
- •Proposing pipeline changes with a shared picture of raw-versus-curated storage boundaries.

- •List your actual sources in the Extract node label, or split it into per-source branches with individual schedules.
- •Move Validate after Transform if your checks run on the curated model instead of raw rows.
- •Rename Metric Models to your dbt or SQL modeling layer, and add orchestrator tasks between stages.
- •Add a dashboard consumer per team by fanning out from Metrics if different groups need different boards.
