🚀 Welcome to Ep 6 of the M Language Series from RR Education!

Today, we explore a powerful optimization technique in Power BI:
👉 *Query Folding* – a process where Power Query pushes transformations back to the data source for better performance.

🎯 What you’ll learn in this episode:
✅ What exactly is Query Folding in Power BI
✅ Which transformations are supported for folding (filter, join, group, etc.)
✅ Why some steps (like Rename Columns) don’t fold
✅ Real hands-on demo with Advanced Editor & SQL Source
✅ How to copy and optimize steps for better performance

💡 If you're aiming for **efficient data models and faster refresh times**, this concept is a must-know.
