Azure Analysis Services scale-out improvement
Published date: 17 September, 2019
Synchronisation of query replicas in Azure Analysis Services scale-out environments now uses an optimised copy API, which significantly reduces synchronisation time on average. The new behavior applies to synchronisation 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 synchronisation copies the data files to a blob storage location dedicated to the query replica instances (separate from the primary-instance location).
