MongoDB as a backend is a bit thorny from a “include it in dogpile.cache”
perspective, b.c. mongo is very open-ended and the means that someone might
want to “cache” inside of it are highly variable (for the same reason, there
aren’t SQL backends included either). That’s why dogpile.cache has a fully
featured plugin API. It would be very easy for oslo.cache to host the
mongodb backend itself, and make it available to dogpile.cache using
standard setuptools entrpoints or direct registration. See the docs for this
