------------------------------------------------+------------------------
The documentation of `get_many` in
django.core.cache.backends.base.BaseCache implies that the implementation
of the method for a database backend can be much faster:
{{{
Fetch a bunch of keys from the cache. For certain backends
(memcached,
pgsql) this can be *much* faster when fetching multiple values.
}}}
However when I look into django.core.cache.backends.db I don't see any
`get_many` implementation meaning that retrieving 1000 entries from the
cache will do 1000 queries instead of just one. This is really sad and
makes this backend a no-go for any heavy usage of the cache.
