Talk about the current status, prospects and opportunities of memory analysis

A memory leak is a gradual decrease in the computer's available memory. It occurs when a program persistently fails to free the temporary memory it uses. JavaScript web applications also often encounter memory-related problems that occur in native applications, such as leaks and overflows. Web applications also need to deal with garbage collection pauses. Although JavaScript uses garbage collection for automatic memory management, effective memory management is still important. In this article we will discuss analyzing memory issues in JavaScript web applications. As you learn about the features, be sure to try out the examples to increase your understanding of how these tools work in practice. Please read the Memory 101 page to familiarize yourself with the terminology used in this article. Note: Some of the features we'll be using are currently only available in Chrome Canary. We recommend using this version to get the best tools for analyzing your application's memory issues. Questions you need to think about Generally speaking, when you think you have encountered a memory leak problem, you need to think about three questions: Does my page take up too much memory?

3. Redis memory analysis (set/get command set)

Introduction: In order to know how Redis uses memory, I analyzed the source code. This article is aimed at the set/get command set, that is, the key and value are simple strings. In addition, Redis also supports commands like hset/hget, whose value is a dictionary, which is left for later analysis. First, let’s take a look at the key data structures used to store data in Redis: 1. zmalloc (
