A live Q&A session with Zach focused on various topics related to data engineering, including the use of Databricks, Spark, and Iceberg. Participants asked questions about capstone projects, technology choices, and best practices for SQL and Spark performance. Zach provided insights into effective querying techniques, the importance of using Delta Lake for data management, and strategies for handling workload distribution in Spark jobs. This session is beneficial for data engineering students seeking practical advice and clarification on their projects and technology stack.
