Problem Analysis

The following is a classic diagram of Dubbo’s operating principle, where service providers and consumers coordinate to achieve automatic address discovery through the registration center.

The main bottleneck faced by the Industrial and Commercial Bank of China is at the registration center and service consumer end; the number of interface-level addresses has reached a scale of hundreds of millions. On one hand, storage capacity has reached its limits, and on the other hand, push efficiency has significantly declined. At the consumer end, the resident memory of the Dubbo2 framework has exceeded 40%, and each address push brings high resource consumption rates such as CPU, affecting normal business calls.

Upgrade Goals

Here is the basic deployment architecture diagram of Ele.me.

Before the upgrade, Ele.me’s microservice framework used HSF2, and inter-unit RPC calls were routed through a proxy. During this time, the number of machines and traffic supported by the proxy increased rapidly. Notably, after subscribing to all address data, the resource consumption and stability of the proxy faced severe challenges.

By upgrading the entire site to Dubbo3, the business line aims to achieve two goals:
