How can I implement caching in my Django app on Heroku?

You can use Django's built-in caching framework along with a caching backend like Redis or Memcached. Heroku offers add-ons for both.

What are the steps to set up Redis on Heroku?

First, add the Redis add-on to your Heroku app using the command: heroku addons:create heroku-redis. Then, configure your Django settings to use Redis as the cache backend.

Can you show me an example of the settings configuration?

Sure! In your settings.py, you can add:

CACHES = {
    'default': {
        'BACKEND': 'django_redis.cache.RedisCache',
        'LOCATION': 'redis://localhost:6379/1',
        'OPTIONS': {
            'CLIENT_CLASS': 'django_redis.client.DefaultClient',
        }
    }
}

What about caching for database queries?

You can use Django's cache_page decorator for views or the cache API for specific queries. Just remember to set appropriate cache timeouts.
