Most people do not understand the knowledge points of this article "what are the test questions often met by Redis", so the editor summarizes the following contents to you, with detailed content, clear steps, and certain reference value. I hope you can gain something after reading this article. Let's take a look at this article "what are the test questions we often see in Redis?"

1. What is the full name of Redis?

It is estimated that many people will be ignored in this problem, but I like it. The full name is Remote Dictionary Server (remote data Service).

2. Why doesn't Redis officially provide the Windows version?

Because the current Linux version has been quite stable, and the number of users is very large, the development of windows version requires more energy, which will bring compatibility and other problems. And Linux has more advantages than Windows in the choice of IO model. We generally develop on window, but the production environment still recommends deployment in Linux, although Microsoft officially provides a windows version of the redis branch on the open source basis of Redis.

3. How does Redis set and verify passwords?

This point is also ignored by many people, and even many people do not set passwords. Set the password: config set requirepass xttblog. Authorization password: auth xttblog.

4. Will any writes be lost in the Redis cluster? Why?

If you don't go deep into this question, you may not know it. Redis does not guarantee strong consistency of data, which in practice clusters may lose write operations under certain conditions.

5. How does the Redis cluster select the database?

If you haven't done a cluster, you probably don't know. You don't know which library exists every time you do set, get, etc. In fact, the Redis cluster cannot make a database selection at present, and the default is 0 database.

The above is about the content of this article on "what are the test questions we often meet with Redis". I believe we all have a certain understanding. I hope the content shared by the editor will be helpful to you. If you want to know more about the relevant knowledge, please pay attention to the industry information channel.
