a framework for implementing application-level request throttling for Django

django-throttle-requests

a framework for implementing application-specific rate-limiting middleware for Django projects

What this module is intended for:

Implementing application-level (or just below) rate-limiting rules. Often, these rules would be expressed as "max # requests within a defined time period". E.g.:

• an IP address may make at most 1500 requests/day
• users with an OAuth access token may make 500 reads/hour and 200 writes/hour

What it is not intended for:

A token bucket or leaky bucket filter: intended primarily for traffic shaping, those algorithms are implemented by firewalls and servers such as nginx.

Installation

1. Install the library with pip:

   sudo pip install django-throttle-requests
   

2. Add the directory throttle to your project's PYTHONPATH.

3. Insert the following configuration into your project's settings:

   THROTTLE_ZONES = {
       'default': {
           'VARY':'throttle.zones.RemoteIP',
           'NUM_BUCKETS':2,  # Number of buckets worth of history to keep. Must be at least 2
           'BUCKET_INTERVAL':15 * 60  # Period of time to enforce limits.
           'BUCKET_CAPACITY':50,  # Maximum number of requests allowed within BUCKET_INTERVAL
       },
   }
   
   # Where to store request counts.
   THROTTLE_BACKEND = 'throttle.backends.cache.CacheBackend'
   
   # Force throttling when DEBUG=True
   THROTTLE_ENABLED = True
   

4. Use the @throttle decorator to enforce throttling rules on a view:

   from throttle.decorators import throttle
   
   @throttle(zone='default')
   def myview(request):
      ...
