Throttling for rate limiting in Django - Cheat Sheet & Quick Revision

Recall & Review

What is throttling in Django REST Framework?

Throttling is a way to limit the number of requests a user can make to an API in a given time. It helps protect the server from too many requests and keeps the service stable.

Name two built-in throttling classes in Django REST Framework.

Two common throttling classes are AnonRateThrottle for anonymous users and UserRateThrottle for authenticated users.

How do you set a rate limit for throttling in Django REST Framework?

You set rate limits in the REST_FRAMEWORK settings using the DEFAULT_THROTTLE_RATES dictionary. For example, {'user': '100/day'} means 100 requests per day per user.

What happens when a user exceeds the throttle limit in Django REST Framework?

The API returns a 429 Too Many Requests response. This tells the user to slow down and try again later.

How can you apply throttling only to specific views in Django REST Framework?

You can add the throttle_classes attribute to a view or viewset and list the throttling classes you want to apply. This way, throttling is not global but limited to those views.

Which Django REST Framework setting controls the rate limits for throttling?

A DEFAULT_THROTTLE_RATES

B THROTTLE_CLASSES

C RATE_LIMIT_SETTINGS

D API_THROTTLE_LIMITS

The DEFAULT_THROTTLE_RATES setting defines the allowed request rates for different throttle classes.

What HTTP status code does Django REST Framework return when a user is throttled?

A 403 Forbidden

B 400 Bad Request

C 401 Unauthorized

D 429 Too Many Requests

When throttling limits are exceeded, the API returns a 429 Too Many Requests status.

Which throttling class is used for anonymous users by default?

A ScopedRateThrottle

B UserRateThrottle

C AnonRateThrottle

D BaseThrottle

AnonRateThrottle limits requests from users who are not logged in.

How can you apply different throttling rates to different API views?

A Set <code>throttle_classes</code> on each view

B Change <code>DEFAULT_THROTTLE_RATES</code> globally

C Use middleware to filter requests

D Modify the database throttle table

You can specify throttle_classes on views to apply throttling selectively.

What is the main purpose of throttling in APIs?

A To speed up responses

B To limit request rates and protect the server

C To authenticate users

D To cache API responses

Throttling limits how often users can call the API to prevent overload.

Explain how throttling works in Django REST Framework and why it is important.

Think about how you would stop someone from calling your API too many times too fast.

Describe how to configure throttling rates and apply throttling to specific views in Django REST Framework.

Consider both the settings file and the view code.
