AxonIQ Con 2023: Powering Event-Driven APIs with Event Sourcing w/ Marc Klefter

Описание: An event-driven API exposes data that is generated within a domain boundary, as event streams for external parties that implement operational and analytical use cases. Event sourcing is a pattern for data storage that records all past changes occurring within a bounded context. It provides internal streams of domain events that can be transformed and published in a suitable format for other bounded contexts to consume in real-time.

In this talk, Marc will explain how and why to use event sourcing to power event-driven APIs. He will highlight why events carrying state are preferable for communicating data across bounded contents instead of fine-grained domain (delta) events, and how to project one event type onto the other. He will discuss the importance of assembling the essential developer and infrastructure support with Axon Framework and Axon Server, and how to select a suitable event broker. And, the talk will conclude with using AsyncAPI to document, discover, and manage events.
