What is the Factory Method Pattern? The Factory Method Pattern is a creational design pattern that creates objects by defining an interface, but defers the specific implementation of the object to the subclass. This means that the Factory Method Pattern allows subclasses to decide which class to instantiate, making code expansion more flexible and easier to maintain. Compared with the Simple Factory Pattern, the Factory Method Pattern no longer relies on a single factory class, but implements object creation through an abstract factory interface. This…

What is the Simple Factory Pattern? The Simple Factory Pattern is a creational design pattern that uses a factory class to instantiate different types of objects. Based on the parameters passed in, the factory class decides which specific class to create. The Simple Factory Pattern is often used to reduce the client code's dependence on specific classes, ensuring that the code is easier to maintain and extend. In the Simple Factory Pattern, the factory class is responsible for the object creation logic, and the client does not need to worry about how to create the object, but only needs to...

Design Patterns is a summary of experience in software engineering, which provides solutions to common software design problems. Although design patterns themselves are not specific codes, they are some reusable design ideas and principles that can help developers write more flexible, maintainable and scalable codes. This blog will introduce the definition, meaning, classification and common examples of each type of design pattern in detail. By understanding these contents in depth, readers can understand how to use them in projects...

Protocol Buffers Basic Introduction and Basic Syntax Introduction In modern software development, data exchange and storage are crucial, and choosing the right serialization protocol is of great significance to improving performance and efficiency. Protocol Buffers (commonly known as Protobuf) is a language-neutral, platform-neutral, and extensible method for serializing structured data developed by Google. This article will introduce the basics of Protocol Buffers…

Using gRPC + Protocol Buffers in Golang to Implement Efficient RPC Services Introduction With the popularity of microservice architecture, remote procedure calls (RPC) are becoming more and more important in modern applications. gRPC is a high-performance, open source, and general RPC framework developed by Google. It uses HTTP/2 as the transmission protocol and supports multiple languages, including Go. This article will introduce in detail how to use gRPC + Protocol Buffers in Golang.

What is the RPC framework? What are the mainstream RPC frameworks? How to implement RPC services in Golang? 1. Introduction to RPC protocol 1.1 What is the RPC protocol? RPC, also known as Remote Procedure Call (RPC), is a computer communication protocol. RPC is a protocol that enables programs to execute subroutines or services in different address spaces. Through RPC, programs can call remote services like calling local functions, thus hiding the network...
