Hello, After Azure SQL database switch (because of internal upgrade of SQL engine/VM or configuration change like upgrade from S2 to S3), we observe a very big CPU spike after 3 to 10 minutes after the switch which will not go away unless we close…
This unit describes the main benefits of using Node.js, and when to use it. Multi-purpose technology You can use Node.js to build a wide variety of production-ready applications. These apps can range from traditional lightweight, high-traffic chat programs to command-line tools and web serve...

9. Are there any disadvantages to using Node.js? A multi-threaded platform can run more effectively and provide better responsiveness when it comes to the execution of intensive CPU computation, and the usage of relational databases with Node.js is already becoming obsolete. 10. Explain the even...
I've created a simple nodejs server and client. They interact with each other via 15000 tcp sockets. client code: 'use strict'; const net = require('net'); for (let i = 0; i < 15000; ++i) { let socket = new net.Socket(); socket.connect(6...
This is a node.js driver for mysql. It is written in JavaScript, does not require compiling, and is 100% MIT licensed. Here is an example on how to use it: var mysql = require('mysql'); var connection = mysql.createConnection({ host : 'localhost', user : 'me', password : 'secr...
Node.js不为每个客户连接创建一个新的线程,而仅仅使用一个线程。当有用户连接了,就触发一个内部事件,通过非阻塞I/O、事件驱动机制,让Node.js程序宏观上也是并行的。使用Node.js,一个8GB内存的服务器,可以同时处理超过4万用户的连接。 另外,带线程的带来的好处,还有操作系统完全不再有线程创建、销毁的时间开销。
1. Node.js Design Patterns The book kicks off by exploring the basics of Node.js, describing its asynchronous single-threaded architecture and the main design patterns. It then shows you how to master the asynchronous control flow patterns and the stream component, and it culminates into a det...
5.10. Measure and guard the memory usage TL;DR: Node.js has controversial relationships with memory: the v8 engine has soft limits on memory usage (1.4GB) and there are known paths to leak memory in Node’s code – thus watching Node’s process memory is a must. In small apps, you ...
