The book "Redis Design and realization", created by the translator Huangjianhong of this document, is being sold in detail about the workings of redis and the principles of its implementation, and is a book dedicated to helping Redis users deepen their understanding of redis and use redis more efficiently. Welcome to visit Redisbook.com and learn more about Redis design and implementation.

The book "Redis Combat", translated by Huangjianhong, a translator of the Redis Command reference, is on the hot sell, and the book provides an insight into the five data structures of Redis, and demonstrates the use of Redis in a series of practical examples. In addition, "Redis combat" also introduced a variety of ways to extend and optimize redis, whether Redis novice or have some experience of redis users, should be able to benefit from this book.

Welcome to visit Redisinaction.com and learn more about the "Redis combat" more relevant information.
