Amazon Athena launches auto-scaling solution for Capacity Reservations

Amazon Athena now offers an auto-scaling solution for Capacity Reservations that dynamically adjusts your reserved capacity based on workload demand. The solution uses AWS Step Functions to monitor utilization metrics and scale your Data Processing Units (DPUs) up or down according to the thresholds and limits you configure, helping you optimize costs while maintaining query performance and eliminating the need for manual capacity adjustments.

You can customize scaling behavior by setting utilization thresholds, measurement frequency, and capacity limits to match your workload needs. The solution uses Step Functions to add or remove DPUs to any active Capacity Reservation based on capacity utilization metrics in Amazon CloudWatch. Capacity automatically scales up when utilization exceeds your high threshold and scales down when it falls below your low threshold - all while adhering to your defined limits. You can further customize the solution by modifying the Amazon CloudFormation template to fit your specific requirements.

The auto-scaling solution for Athena Capacity Reservations is available in AWS Regions where Capacity Reservations is supported. To get started, see Automatically adjust capacity in the Athena user guide.
