First of all, redis uses decentralized design and this understanding is not in place. Redis distributed mode, with master-slave and cluster two, redis community cluster scheme Redis Cluster is a decentralized design. Let's take a look at the evolution of Redis:

Interface processing logic: obtain nationwide regional information. Obtain information from mysql for the first time. After obtaining information, hset to Redis.

Abstract: On July 22, 2021, the Official Redis and the open source Redis community have released an announcement, disclosed the CVE-2021-32761 Redis (32-bit) remote code execution vulnerability. So how do you nip in the bud for such database security holes?

One, the preface in the development of our daily, they are using the database for data storage, as a result of the general system task in high concurrency usually doesn't exist, so it looks like there is no problem, but when it comes to the demand of the large amount of data, such as some snapping up the goods, or the home page views moment is larger, A system that uses only a database to store data can be disk-oriented and slow to read/write...

Recently I am preparing for an interview, and I will summarize what I have seen. Redis supports set liset and other data types. Memcache supports simple data types. 2, persistent Redis support data fall persistent storage Memcache does not support data persistent storage 3, distributed storage Redis support master-slave replication mode Memcache can use consistent...

Probably most of the answers are string, hash, list, set, zset. Of course, there's no mistake about this answer, but believe it and your interviewer will probably hear it.

This article will take Redis Bigkey as the theme for technical development. Through understanding the high performance of Redis, the harm of Bigkey, the reasons for its existence, four solutions, and the introduction of practical simulation, we will understand, discuss and learn Redis together.

Redis (a) how to achieve a fixed size cache? How does Java reboot its memory data without losing it? In addition to the expire principle, there is an additional way in which Redis will be implemented in the expire principle. In addition to the expire principle, there is an additional way in which Redis will be implemented. Write it down here so you can...

In this section, let's learn how to implement a removeListener for removing listeners like the Guava-Cache and a slowListener for monitoring slow logs like the Redis SlowListener.
