Building applications to serve actual users is really hard! Traffic spike, data accumulates, queries becomes slow, response time suffer and you sre left completely baffled! In this workshop we'll optimize real-life scenarios in a Django application using advanced indexing techniques in PostgreSQL. We will also identify and tackle concurrency issues and experiment with different approaches to prevent them, without bringing the system to a halt. By the end of this workshop you'll learn how to prepare your Django application for the real life.

Django signals are extremely useful for decoupling modules and implementing complicated workflows. However, the underlying transport for Django Signals makes them unreliable and subject to unexpected failures. In the talk I demonstrate several strategies for decoupling modules, including Django Signals, and discuss different aspects such as user experience and fault tolerance. Finally, I present an alternative underlying transport implementation for Django Signals using the new tasks framework in Django 6 that addresses the shortcomings of all other approaches. The alternative implementation makes Django Signals reliable for mission critical workflow and for applications that require high reliability and fault tolerance.
