Business value

Support high user-concurrency workloads for large-scale deployments of semantic models (datasets) in Power BI Premium. Management of query scale out in Power BI Premium is largely automated for customers.

Feature details

Query scale-out in Power BI Premium enables user queries to be load balanced across multiple dataset read replicas in a pool of Power BI Premium Gen2 nodes. This speeds up query response times for high user-concurrency workloads.

Additionally, dataset refresh operations enjoy increased isolation from the read replicas to protect user queries and improve performance.

Management of query scale-out in Power BI Premium is highly automated compared to other platforms, such as Azure Analysis Services. Adding and removing read replicas is performed dynamically based on usage.
