I am importing and using cache as this:
from django.core.cache import cache
cache.add('a','b',60)
I haven't defined any settings for the cache in settings.py ,then where does this cache come from and where is it stored.
Django documentation says: "This object is equivalent to caches['default']", but what is the default ?

Unless we explicitly specify another caching method in our settings file, Django defaults to local memory caching. As its name implies, this method stores cached data in RAM on the machine where Django is running. Local memory caching is fast, responsive, and thread-safe.
For convenience, Django offers different levels of cache granularity: You can cache the output of specific views, you can cache only the pieces that are difficult to produce, or you can cache your entire site. Django also works well with “downstream” caches, such as Squid and browser-based caches.
If you would like to store cached data in the database, Django has a backend for this purpose. To save cached data in the database, you just need to create a table in the database by going to the settings.py file, setting BACKEND to django. core. cache.
What is Redis? Redis is an in-memory data structure store that can be used as a caching engine. Since it keeps data in RAM, Redis can deliver it very quickly. Redis is not the only product that we can use for caching.
In https://docs.djangoproject.com/en/stable/topics/cache/#local-memory-caching says:
Local-memory caching
This is the default cache if another is not specified in your settings file
