How does it handle data quality?

It integrates data quality tests and validation patterns using dbt testing frameworks and tools like Great Expectations to ensure reliable analytical outputs.

Does this skill support dbt incremental models?

Yes, it provides patterns for implementing incremental data loads and merge strategies to handle large datasets efficiently while minimizing compute costs.

Which orchestration tools are covered?

The skill includes implementation patterns for industry-standard tools like Apache Airflow, Dagster, and Prefect, helping you choose the best fit for your architecture.

Can I use this for performance optimization?

Absolutely. It includes specific migration guides for moving from pandas to polars or PySpark to handle larger data volumes and significantly increase processing speed.
