1. Preface Online services are rarely deployed in a single machine, which does not meet the needs of the three high architecture of the Internet. Once the service is suspended, high availability is out of the question. In addition, the default maximum 200 concurrent processing of Dubbo single machine does not meet the so-called high concurrenc ...

This article focuses on a simple example of Java using gRPC. preface We can't just look at principles and ignore practice, nor can we just focus on practice and ignore principles. We should give consideration to both! In the previous two articles [RPC basic series 1] talk about RPC and [RPC basic series 2] understand the basic princip ...

Following the previous section, Teach you to write an RPC framework (1) We handwritten a Spring Boot Starter and started the first step of building our own wheels. In this section, let's continue to complete the RPC framework! V. user defined annotation For my requirements, when using my RPC framework, the service provider can tell the fram ...

preface Before we talk about this, let's take a look at the relevant background knowledge. Introduction to RPC RPC is short for Remote Procedure Call. Remote service call.

If a connection has no heartbeat for a long time, it needs to be disconnected in time, otherwise the server will ...
