Building high-performing Power BI solutions requires both efficient DAX and well-designed security. In this session, we’ll dive into proven techniques for optimizing DAX calculations and implementing Row-Level Security (RLS) without compromising performance. Learn how to leverage tools such as DAX Optimizer and Best Practice Analyzer to identify performance bottlenecks, optimize DAX code, and ensure scalable semantic models. We will also explore various RLS patterns, from dynamic security to complex design, and discuss strategies to minimize their performance impact in large datasets. Whether you are fine-tuning an enterprise model or designing secure, responsive dashboards, this session will equip you with practical approaches to maximize efficiency and deliver trusted insights at scale.
