Modern data engineering requires agility that traditional batch processing struggles to provide. This hands-on talk tackles the complex challenge of wrangling unpredictable, unstructured data streams into actionable formats. Through a live architectural walkthrough, we will demonstrate how to combine Gemini's reasoning capabilities with Cloud Run to execute dynamic, real-time schema mapping. Finally, we will integrate dbt as an external orchestrator to handle the subsequent data transformations, providing a complete, production-ready blueprint for modern data pipelines.
