Comment Django for the 80% solution (Score 2) 287
We've been building a suite of tools using Django that combine near-real-time event processing and offline analytics. It's been very useful and flexible; the data model abstraction is clean, and we can target different databases with a couple of lines of config file change. We're integrating some Javascript and other visualization tools in our UIs, and finding it pretty easy to support in the Django framework. Performance scales with resources fairly linearly, the overhead has been very manageable, and it integrates into almost any security framework. I've seen nothing to convince me we need to look at a different framework.
