Mastering Python Design Patterns - Second Edition

Real-world examples

Since this is an important feature for Restful APIs, the frameworks have built-in support or third-party modules to implement throttling. The following are some of the examples:

• The built-in support in Django-Rest-Framework (see https://www.django-rest-framework.org/api-guide/throttling/)
• Django-throttle-requests (https://github.com/sobotklp/django-throttle-requests) is a framework for implementing application-specific rate-limiting middleware for Django projects
• The flask-limiter (https://flask-limiter.readthedocs.io/en/stable/) provides rate limiting features to Flask routes

And we can find throttling implemented in the big Cloud players' services themselves, such as AWS API Gateway
