Event-Driven Architecture

Purpose

Design event flows that survive redelivery, reordering, and consumer failure — because all three will happen, and the broker's guarantees are weaker than most designs assume.

When to Use

• Introducing a message broker or queue.
• Designing event schemas that other teams will consume.
• Debugging duplicate processing, lost messages, or stuck consumers.
• Evaluating event sourcing for a subsystem.
