Quota Management Flow

Flow Diagram

The Quota Management Flow is a combination of the Client-Side Limiting Flow and the Prioritized Queue Flow. It regulates API requests by enforcing quotas while also managing traffic queues based on priority.

This ensures that API resources are used efficiently, controlling access dynamically based on set limits and priority levels. It’s particularly useful for environments with varying needs, like production vs. staging, where both quotas and prioritization are crucial.

This flow allows for flexible quota management based on attributes like URLs or headers, while also assigning different priority levels to user groups to ensure critical traffic is processed first.

Scenarios​

  1. Dynamic API Quotas: Set quotas for different environments, such as production and staging, ensuring controlled and efficient usage.
  2. Priority Traffic Management: Ensure critical API requests are prioritized for quicker processing.
  3. Prevent Overload with Queuing: Delay excess requests in a queue to manage traffic efficiently without immediately denying service.
  4. Custom Response Handling: Provide tailored responses when quotas or queue limits are exceeded, giving feedback on retry options.
  5. Fair Resource Allocation: Balance resource usage across different users or environments by enforcing quotas and priority management.
