This document discusses the WALD stack, a modern and sustainable analytics stack combining Snowflake, Airbyte, dbt, Lightdash, and optionally Streamlit. It provides an example of analyzing Formula 1 racing data using these tools, with Airbyte ingesting data into Snowflake, dbt for transformations, Lightdash for visualization, and dbt with Snowpark for machine learning predictions. The speaker argues the WALD stack is flexible for many use cases from analytics to full data products at scale.
