Amazon Cognito now allows you to increase or decrease your provisioned API rate limits on demand. Cognito has default rate limits for the maximum number of operations per second that you can perform in your user pools in each AWS Region, and you can purchase additional limits on adjustable API categories. With the new on-demand model, you can adjust your rate limits up or down more quickly to match your application’s traffic patterns.

Previously, to adjust your Cognito API rate limits, you would request an increase through Service Quotas, where requests are manually reviewed. This meant you had to plan rate limits in advance ahead of anticipated traffic spikes. Now, you have a new self-service experience to set your desired Cognito rate limit up to the account-level max limit using the Amazon Cognito console or the new limit provisioning API operations. Rate limit changes take effect immediately.

Self-service provisioned limits are available for adjustable API categories in all AWS Regions where Amazon Cognito is available. For pricing details of this add-on feature, see Amazon Cognito pricing page. To get started, see developer guide.
