rRPC, or Reactive Remote Procedure Call, is an emerging method that enhances the traditional RPC model by incorporating reactive programming principles. This approach is particularly useful in systems where responsiveness and scalability are critical, such as microservices architectures. By leveraging a non-blocking, event-driven paradigm, rRPC enables more efficient use of system resources and improves the overall performance of distributed applications.
The "assess" ring indicates that rRPC is a promising technology worth exploring, but it may still be maturing or not yet widely adopted. It belongs in the "methods-and-patterns" quadrant because it represents an innovative approach to designing communication patterns in software architecture. As organizations increasingly adopt microservices for their scalability and flexibility, exploring advanced techniques like rRPC can provide significant benefits in terms of system efficiency and responsiveness.
