Hi Andrew

I don't believe any work has started on async caching in core. However
there is a plan in DEP 9, the document that outlines how asynchronous
caching will work, using suffixed methods like get_async() etc. See
https://github.com/django/deps/blob/master/accepted/0009-async.rst#caching
. This section specifically says that the default implementations will back
onto the sync methods by default, so built-in cache backends won't need to
all be converted (at once?).

I think a good start would be making your aioredis-based backend in a third
party package, using the future naming scheme `*_async`. It could be
informative to have a working backend using this interface, and if you
encounter any edge cases whilst creating it.

Thanks,

Adam
