Allard Buijze is presenting:

Performance aspects of Axon-based CQRS/ES systems

In this session, we'll zoom into a specific aspect of Axon-based CQRS/ES systems: performance. While CQRS/ES is often touted as a great performance booster (through query simplification and eventual consistency), in reality, there are some challenges. Large event stores, or individual aggregates with large numbers of events, may show horrible performance. Also, replaying the event stream into a new read model sounds easy in principle, but becomes challenging when talking about billions of past events.

This session will begin with a fast-paced review of the core CQRS/ES principles and their implementation in Axon. After that, we'll focus on the various performance challenges and approaches to solving them.
