Dubbo3 Application-Level Service Discovery Design

Mon, 30 Jan 2023 00:00:00 +0000

Objective

Significantly reduce resource consumption during the service discovery process, including increasing the registration center’s capacity limit and reducing resource usage for consumer address resolution, allowing the Dubbo3 framework to support larger-scale cluster service governance and achieve unlimited horizontal scalability.
Adapt to underlying infrastructure service discovery models such as Kubernetes, Service Mesh, etc.

Background

We start with the classic working principle diagram of Dubbo; from its design inception, Dubbo has built-in capabilities for service address discovery. Providers register their addresses with the registration center, and consumers subscribe to receive real-time updates about address changes from the registration center. Upon receiving the address list, consumers initiate RPC calls to providers based on specific load balancing strategies.
