Sydney Power BI User Group May 2022

Hello Sydney Power BI User Group Members

In this meetup, we had the pleasure of welcoming back Chris Webb from the Microsoft CAT team. Chris talked on the topic of Performance Tuning Power Query and Dataflows in Power BI

Topic: Performance Tuning Power Query and Dataflows in Power BI

Speaker: Chris Webb

Whether you are transforming data in the Power Query Editor in Power BI Desktop or using Power BI Dataflows it's important that your Power Query queries run as quickly as possible. In this session you'll learn how to diagnose Power Query performance problems using features like SQL Profiler, Query Diagnostics and Query Plans, and then fix them by optimising your code, ensuring query folding takes place, increasing the resources available to the Power Query engine and using the Enhanced Compute Engine in Dataflows.
