November 2018 Meeting Information

What is CQRS+Event Sourcing and Why Should Java Developers Care?

We are happy to announce that Reza Rahman will be our special guest for this month's meeting.

CQRS (Command Query Responsibility Segregation) is a design pattern that originates in DDD (Domain-Driven Design) and emphasizes strictly separating reads from updates in the application. Event Sourcing is a closely related technique that stores state as a series of events as opposed to only keeping track of the latest data. While these concepts are important on their own right, they are especially important for microservices development.

In this heavily demo driven session we explore CQRS and Event Sourcing in detail using the Axon Framework and Java. At the end of the session you should have a good idea if CQRS and Event Sourcing are for you and how Axon helps in implementing these concepts.

Meetings are held every second Tuesday of the month at the Dorothy Young Center for the Arts, Room 106, at Drew University starting promptly at 6:30pm. Meetings are open to the public, and visitors are encouraged to join ACGNJ.
