We are excited to announce that starting today all new Azure Cosmos DB accounts will be able to use our new public preview feature for autoscale, dynamic scaling per partition and per region. This dynamic scaling will provide you with the flexibility to independently scale non-uniform workloads resulting in greater efficiency and savings.
Dynamic scaling per partition and per region allows each partition and each region to scale up and down independently based on usage. Previously, all partitions scaled uniformly based on the most active partition. This works well for scenarios with even traffic across all partitions. However, it could cause unnecessary scaling if only a single or a few partitions are active. Database workloads that have a highly trafficked primary region can take advantage of this autoscale improvement to save on cost.
