Event Sourcing in Production - Tactics and Patterns for Real-World Applications

Explore real-world tactics for managing Event Sourcing in production during this 30-minute conference talk at EuroPython 2024. Delve into practical patterns to avoid pitfalls and bottlenecks while implementing Event Sourcing using the `eventsourcing` Python library. Learn how to adapt business logic without losing data or past states as domain understanding evolves. Discover techniques for handling the three key aspects of successful event-sourced applications: evolution, projection, and runtime. Understand how to create new projections and replay history to support optimal read-models, and explore different approaches to running event-sourced systems in typical web applications, both synchronously and asynchronously. Gain insights into distributed processing and eventual consistency. Some familiarity with Event Sourcing, Domain Driven Design (DDD), and Command Query Responsibility Segregation (CQRS) is recommended for this talk.
