PyCon, the gathering for the community using and developing the open-source Python programming language. This is the first year of the PyCon Pune where the community will meet for two days of talks and working on upstream projects in two days of dev sprint. CFP ends on 30th November AoE.
Django on Steroids -- Lessons from Scale
This talk summarizes my learnings (best practices and gotchas) by using Django as the core application engine in a production application for the past two years at DoSelect. I’ll discuss about the common, and not-so-common patterns you should take care of when you hit scale with Django, complete with real-life scenarios. Topics include (non-exhaustive) -- production server configuration, best practices when using Django as provider for an SPA (Single-page app), caching, query optimization while using the ORM, gotchas while using async tasks, et al.
The talk is intended for people who have a basic knowlegde of Python / Django, know how web applications work in general. Key take-aways would be things you can directly drop into your production Django application for better performance.
- Tuning your web server configuration (using Nginx and Gunicorn as example)
- Caching whatever you can, but no more
- How to write Django ORM queries that scale
- When NOT to write Django ORM queries
- Async tasks while maintaining data consistency
- Using Django with an SPA front-end
- Scaling Postgres while scaling Django
- Optmizing async task runners
(more stuff to be added)
The talk will include real-world code examples while illustating the points above -- explaining what we faced in production, and how we solved it (and then realized that’s what we should have done in the first place). I plan to have a bit longer Q&A session, due to the nature of this talk.
Preliminary knowledge of Python and Django.
