 # CustomerIntent: As a database adminstrator, I want to fine tune autoscaler for specific regions or partitions so that I can balance an uneven workload.

 # Per-region and per-partition autoscale (preview)
 
-By default, Azure Cosmos DB autoscale scales workloads based on the most active region and partition. For nonuniform workloads that have different workload patterns across regions and partitions, this scaling can cause unnecessary scale-ups. With this improvement to autoscale, the per region and per partition autoscale feature now allows your workloads’ regions and partitions to scale independently based on usage.

+> By default, this feature is only available for Azure Cosmos DB accounts created after **November 15, 2023**. For customers who can significantly benefit from dynamic scaling, Azure Cosmos DB is progressively enabling the feature in stages for existing accounts and providing GA support, ahead of broader GA. Customers in this cohort will be notified by email before the enablement. This update won’t impact your account(s) performance, availability, and won't cause downtime or data movement. Please contact your Microsoft representative for questions.
 
 This feature is recommended for autoscale workloads that are nonuniform across regions and partitions. This feature allows you to save costs if you often experience hot partitions and/or have multiple regions. When enabled, this feature applies to all autoscale resources in the account.
