New Django libraries: Cache Machine and multidb

Feb 10 2010

Yesterday, the Mozilla webdev team released a few reusable libraries that are helping us scale out the new Django-based version of addons.mozilla.org.

Cache Machine hooks into the Django ORM to provide automatic object caching and invalidation for database queries. We have a separate post about how Cache Machine works.
multidb-router is a round-robin master/slave database router. It’s similar to the router from the Django docs, in a package with its own documentation .

This is very similar to my as-yet-unreleased project “johnny-cache”, except that johnny caches any type of query, it supports versions 1.x of django, and its invalidation is potentially a lot more zealous. I started conceptual work on Johnny a year ago, but have only gotten around to reimplementing it for open-source consumption recently. The docs are:

http://dev.jmoiron.net/johnny/

and the hg repos:

http://dev.jmoiron.net/hg/johnny-cache/

I expect to have a release on pypi sometime within the next few weeks. I’d love to ask you some more questions about your invalidation strategy; there may be room in this world for a hybrid approach 🙂
