Azure Analysis Services scale-out improvement
Published date: 17 September, 2019
Synchronization of query replicas in Azure Analysis Services scale-out environments now uses an optimized copy API, which significantly reduces synchronization time on average. The new behavior applies to synchronization operations by default.
Scale-out in Azure Analysis Services enables client query distribution across query replicas, reducing response times for high-concurrency workloads. Query replica synchronization copies the data files to a blob storage location dedicated to the query replica instances (separate from the primary-instance location).
