Parameter Store, a capability of AWS Systems Manager, now supports up to 10,000 transactions per second (TPS) for the GetParameter API, increased from the previous 3,000 TPS limit. Parameter Store allows you to securely store configuration data and secrets as hierarchical key-value pairs. You can flexibly store parameters such as API keys, subnet IDs, and passwords, and you can reference those parameters in your code and through AWS services such as AWS Lambda, Amazon EC2, and AWS CloudFormation. This increased API limit makes it easier to use Parameter Store to support high-traffic applications and demanding workloads without sacrificing performance due to API throttling.

The 10,000 TPS limit is available when you enable the higher throughput setting in your Parameter Store account. If you already have the higher throughput setting enabled, you can start using 10,000 TPS today with no additional steps required.

To turn on higher throughput for Parameter Store, visit the documentation. For information about pricing, visit the Systems Manager Pricing page. This feature is available in all AWS Regions where AWS Systems Manager is available.

9/8/2023: 10,000 API transactions per second is only supported for the GetParameter API. To confirm API limits for other APIs such as GetParameters and GetParametersByPath, see AWS Systems Manager endpoints and quotas.
