This article mainly introduces what are the three main characteristics of Redis, which can be used for reference by friends who need it. I hope you will learn a lot after reading this article. Next, let the editor take you to learn about it.

Redis is a single-threaded server. Its design does not benefit from multicore cpu. People can install multiple redis instances to improve the utilization of multicore cpu. It is unfair to compare redis with more threaded storage servers. Each request is cached in one thread, and only one thread can process the request at a time.

Redis actually adopts the concept of thread closure, enclosing tasks in a single thread, which naturally avoids thread safety problems, but for composite operations that rely on multiple redis operations, locks are still required and may be distributed locks.

Summary: redis is thread safe

Redis is an open source, advanced key-value storage, and the perfect solution for building high-performance, scalable Web applications, is thread-safe.

There are three main features of Redis:

The Redis database is entirely in memory, and the disk is used only for persistence.

Compared with many key-value data stores, Redis has a relatively rich set of data types.

Redis can copy data to any number of slave servers.

Thank you for reading this article carefully. I hope the editor will share what the three main features of Redis are helpful to everyone. At the same time, I also hope that you will support us, pay attention to the industry information channel, and find out if you encounter problems. Detailed solutions are waiting for you to learn!
