Now they are shipping a built in Redis cache back-end?
That would be so totally crazy that I am having trouble believing this headline.
How about "Django 4.0 will include built-in Redis cache support"
no. actual link as you surmised states:
This PR aims at adding support for Redis to be used as a caching
backend with Django. As redis is the most popular caching backend,
adding it to django.core.cache module would be a great addition for
developers who previously had to rely on the use of third party
packages.
In the PHP world, for example, acpu is a popular user-facing cache that uses mmap so that it works cross-process, then you can move to redis if you want to scale across more than one host.
