Dnipropetrovsk Discussion Meetup: CQRS Problem / Solution

    On Tuesday, January 13, the Cyclum Dnipropetrovsk office organizes a meeting dedicated to the architectural principle of CQRS (Command and Query Responsibility Segregation) .


    CQRS (Command and Query Responsibility Segregation) is an analogue of DDD (Domain-driven design) in distributed systems. It is based on the CQS pattern.(Command Query Separation). CQS is as follows: any method in the application is either a query (Query) that returns data, or a command (Command) that modifies the data. The CQRS pattern is quite effective to use together with the Event Sourcing approach, the idea of ​​which is to record every system change in the store (EventStore). Examples of real use of 2 technologies will also be given and reviewed.

    CQRS is a new and promising architectural approach, so many interesting questions are planned to be discussed:
    Big data + CQRS
    Sagas alternatives for dummies
    The problem of long rearrangement of projections
    Applications in which CQRS will not work
    Combining CQRS approach with traditional
    Node.JS (Go) + CQRS?

    Both experienced CQRS developers and teapots will participate in the discussions.
    the event is free, by prior registration http://goo.gl/forms/rOK4FuvXpz
