Example microservices using ddd-4-java and cqrs-4-java libraries and Greg Young's EventStore for Event Sourcing. Events, not really necessary but it is a good practices to update your relational db in the context of transaction and just emit event that will signal that the read model has to change. - fuinorg/ddd-cqrs-4-java-example It has two microservices (Command & Query) for each framework ( Quarkus & Spring Boot ) and also shows how to build aggregates, entities and that are stored in the Event Store using event sourcing. Here I am going to share a custom toolkit wrapped as a spring boot with AKKA persistence starter to act as a read made toolkit for event driven asynchronous non blocking flow API , event sourcing and CQRS implementation within spring boot services which can be part of spring cloud micro-services infrastructure . We already introduced CQRS architectures a while ago here. An intro to the Axon framework (v4) by building a simple CQRS and Event Sourcing example application. 1.
