The advanced PDF document of Java architecture obtained from Tencent T3-3 boss, with rich pictures and texts, really fragrant

With the advent of the 5G and cloud era, architecture design capabilities have increasingly become a prerequisite for advanced Java development engineers. How to quickly digest abnormalities and sudden traffic has become the main focus of high-quality sticky services. For example, when interviewing for a back-end development position, the interviewer will not only examine basic capabilities**, but will also focus on the thinking logic behind high-concurrency, distributed and other architecture-related technologies, such as: distributed, database, microservice, load Balance, Redis, RPC, etc.

But these technologies include N many optimizations and N many details. For some programming friends, because they do not have access to the first-line actual architecture design, they have no chance to touch these. Thinking about it, it is a bit wronged. It's not that I don't want to learn, I really can't find resources!

It just so happened that I worked hard and stayed up all night to sort out 30 PDF documents with detailed illustrations and advanced technology of java architecture to share with you for assisting learning. You can see what you need and get what you need:

Go directly to the topic, **Because there are too many details in the pdf document, only the chapters with some knowledge points are edited. Under a rough introduction, each chapter has more detailed content in the small nodes! But it has been compiled into a detailed 31 PDF documents: **Linux+JVM+ Spring+MySQL+Mybatis+design pattern+distributed+microservice+multithreading+ActiveMQ+Zookeeper+Dubbo+SpringCloud microservice+Nginx+SpringBoot+NIO+ Thread pool principle analysis & deepening of locks, friends in need can get a free way at the end of the article!

JVM parameter tuning and garbage collection mechanism algorithm analysis

The virtual machine has always been the hardest hit area for interviews. Many small partners are planted on it and need to be prepared carefully. The high frequency test sites are as follows:

JVM basic concepts, runtime data area analysis, in- depth analysis of JVM objects, such as: class loading principle, parent delegation model, source code analysis (focus) , JVM optimization, garbage collection, efficient concurrency, etc.

MySQL database optimization

In Internet companies, the most commonly used database is MySQL, which must be mastered. First, let's take an xmind picture, which lists the necessary knowledge points in the interview for your reference. I hope it can help you quickly get started.
