• Are CQRS commands part of the domain model? - I published an online course about CQRS a couple months ago, and since then I realized that there are some topics I didn’t put enough emphasize on in that course, or didn’t cover at all. In the next several blog posts, I’m going to fill this gap. [Enterprise Craftsmanship]

• CQRS replay performance tuning - Command Query Responsibility Separation (CQRS) has become a popular pattern to avoid complex, and therefore slow, database queries in applications. With CQRS, queries are served from dedicated read models that are optimized for the query’s specific needs. This ensures that queries are as simple as possible, and therefore as fast as possible. The read models need to be initialized and kept up to date with the primary storage (the command side). This is done most easily if the primary storage is event-based: the Event Sourcing (ES) concept. Axon offers a mature and popular implementation of the CQRS/ES concepts on the JVM, but several other implementations exist. [Axon Framework and related blogs via Aggregater Linklog]
