Reactive programming

Reactive programming is emerging as a clear alternative to traditional architectures. According to the manifesto, these changes are happening because application requirements have changed dramatically in recent years. Only a few years ago a large application had tens of servers, seconds of response time, hours of offline maintenance and gigabytes of data. Today applications are deployed on everything from mobile devices to cloud-based clusters running thousands of multi-core processors. We need architectures that know how to take advantage of the performance of the cores in an efficient way. Systems built as Reactive Systems are more flexible, loosely-coupled and scalable

According to the manifesto the main advantages are

Responsive: The system responds in a timely manner if at all possible.
Resilient: The system stays responsive in the face of failure.  
Elastic: The system stays responsive under varying workload.
Message Driven: Reactive Systems rely on asynchronous message-passing to establish a boundary between components that ensures loose coupling, isolation and location transparency

One of the platforms that is betting on this type of architecture is Spring Framework. Bit by bit Spring is incorporating this architecture in all its projects, but sometimes it is not easy to implement because it is an incipient technology. 

To make it easier to learn, I leave you a link to a personal project, where it is made entirely with reactive programming and that can be helpful to learn their techniques when approaching a project of this kind. The project is divided into the following sections:

  •  carisa-core: A framework of support. In this framework there are different classes to handle aggregate in Nosql databases.


I hope it helps you...
