Preface Last mentioned to improve our RPC framework, this week take the time to explore the native NIO non-blocking network programming ideas that JDK provides to us.NIO libraries were introduced in JDK 1.4.NIO makes up for the deficiency of the original I/O by providing high-speed, block-oriented I/O in standard Java code. Main differences ...

TCP sticking / unpacking TCP is a "flow" protocol. The so-called flow is a string of data without boundary. You can think of the running water in the river. They are connected in one piece and there is no boundary between them. The bottom layer of TCP does not know the specific meaning of th ...

Preface In the actual development process, we often encounter businesses that require multi-threaded concurrency. Finally, we need to summarize the tasks completed by each thread, but the main thread usually ends earlier than the sub-threads. If you want to wait for each sub-thread to finish before running the main thread, you need to identify ...

Using Java to build a simple example of Netty communication Students who have seen the dubbo source code should know that the underlying communication using the dubbo protocol is to use netty for interaction. Recently, after reading the netty part of dubbo, they wrote a simple example of netty communication. Source address of this paper: implem ...

1. background With the popularity of microservice architecture, services are divided according to different dimensions. A request often involves multiple services. And many services may be distributed in thousands of servers, across multiple different data centers. In order to locate and solve the fault quickly and analyze the application perf ...

In the previous version, netty was used to implement a simple one-to-one RPC, which required manual service address setup and was more restrictive. In this article, using zookeeper as a service registry, local service information is registered in zookeeper at service startup. When a client initiates a remote service call, the address of the ser ...

01 RPC overview The following picture, which many small partners have seen, is a picture on Dubbo's official website describing the evolution of the project architecture. It describes the configuration and organization of each architecture. When the website traffic is very small, only one application ...
