Udi Dahan

Event-driven architecture experts Udi Dahan and Laila Bougria discuss the challenges of coordinating work in event-driven architectures. They explore the differences between orchestration and choreography, the types of events and their contexts, evolving contracts in a message system, observability tools, and the role of SLAs. They emphasize evaluating the entire workflow and the necessity of each step in complex workflows.

In this engaging discussion, Udi Dahan, a pioneer in service-oriented architecture and co-originator of the CQRS pattern, dives into the nuances of Command Query Responsibility Segregation. He explains how separating read and write models can simplify complex domains, and outlines the benefits of event sourcing for preserving object state. Udi also touches on vital infrastructure choices and emphasizes the importance of collaborating with domain experts to select the right architectural patterns for specific needs.

Udi Dahan discusses the CQRS architectural pattern, its relation to the command pattern, event ordering, event sourcing, and its popularity in different programming communities. He also provides resources for learning more about CQRS.
