How does a Power BI consultant optimize performance for large datasets?

[royben239]

Handling large datasets requires efficient data modeling, query optimization, and performance tuning. A Power BI consultant must use Aggregations, Star Schema modeling, indexing, and partitioning to enhance report speed. Choosing the right storage mode (Import vs. DirectQuery) affects performance. Poor optimization results in slow dashboards, excessive memory consumption, and inefficient processing. A skilled Power BI consultant ensures reports are lightweight, responsive, and scalable by using query folding, compression techniques, and optimized DAX formulas, enabling businesses to analyze massive datasets without performance bottlenecks.
