The interview questions of large companies reflect the requirements of special technology in production scenes from a certain aspect. The problem of high concurrent interview was once the patent of big companies such as BAT, and now it has spread to almost the whole industry related to Java projects. For example, interview questions involving Java NIO, Reactor mode, high-performance communication, distributed lock, distributed ID, distributed cache, high concurrency architecture and other technologies have changed from the previous bonus questions to the current basic questions, which also reflects the technology stack necessary for developing Java projects: distributed spring mvc, Redis cache, distributed search ElasticSearch, distributed collaborative ZooKeeper, message queue Kafka, and high-performance communication framework Netty.
Netty, Redis, Zookeeper High Concurrent Operations analyzes the underlying principle of high concurrent IO in a simple way, analyzes the high performance mode of Reactor in detail, and introduces the Java asynchronous callback mode with pictures and texts. Mastering these basic principles can help you solve some practical problems in Java background development.
Chapter *** 12 of this book mainly introduces Netty, a high-performance communication framework, and introduces Netty's important components such as EventLoop, Handler, Pipeline, ByteBuf, Decoder and Encoder in detail, and then introduces the actual design and module implementation of a single IM. This book also introduces the usage of ZooKeeper, Curator API, Redis and Jedis API in detail, so that everyone can have the ability to design and develop highly concurrent and extensible systems.
Because there is more content, I will put some screenshots this time. If you don't like it enough, you can have a deeper understanding of this note and master it thoroughly. Just forward and reply to 666 by private message to get a free way to get it!
