Create a new Bruin template that demonstrates a bronze-to-silver data pipeline pattern using BigQuery as the destination. This template will use either frankfurter or chess as the data source (since they don't require credentials) and showcase a complete ingestr -> transformation workflow.
This template should be able to initialized with bruin init template-name

Template Structure

Bronze Layer (Ingestr Asset):

• Raw data ingestion using ingestr from frankfurter or chess API
• No transformations, just data extraction to BigQuery

Silver Layer (SQL or Python Asset):

• Aggregates and cleans bronze data from BigQuery tables
• Demonstrates typical transformation patterns

Implementation

Create templates/bronze-silver-bigquery/ with:

• .bruin.yml with BigQuery connection
• README.md with setup instructions
• pipeline.yml
• Bronze asset: assets/bronze_raw_data.asset.yml (ingestr from frankfurter/chess)
• Silver asset: assets/silver_aggregated.sql (BigQuery SQL transformation)

Acceptance Criteria

• Template created in templates/bronze-silver-bigquery/
• Bronze layer uses ingestr asset to extract data from frankfurter or chess source (no credentials needed)
• Silver layer aggregates bronze data with BigQuery SQL transformations
• Documented with clear setup and usage instructions in templates documentations
• Can be initialized with bruin init bronze-silver-bigquery
• bruin validate passes successfully
• Assets have meaningful quality checks (column checks, custom checks)
• bruin run executes the full pipeline successfully
