Editor to share with you what Redis refers to the database, I believe that most people do not know much about it, so share this article for your reference, I hope you can learn a lot after reading this article, let's go to understand it!

Redis is a very fast, open source, written in ANSI C language, network-enabled, memory-based and persistent logging, non-relational, Key-Value database, and provides API in multiple languages.

Redis is a high-performance key-value database. The emergence of redis makes up for the deficiency of key/value storage such as memcached to a great extent, and can play a good complementary role to relational database in partial situations. It provides clients such as Java,C/C++,C#,PHP,JavaScript,Perl,Object-C,Python,Ruby,Erlang, which is easy to use.

Redis supports master-slave synchronization. Data can be synchronized from the master server to any number of slave servers, which can be the master server associated with other slave servers. This makes it possible for Redis to perform single-layer tree replication. Save the disk can intentionally or unintentionally write to the data. Because the publish / subscribe mechanism is fully implemented, when the slave database synchronizes the tree anywhere, it can subscribe to a channel and receive the complete message release record of the master server. Synchronization is helpful for scalability and data redundancy of read operations.

Main features of Redis

Advanced data structures: provide five possible data types for values: strings, lists, collections, hashes, and ordered collections. Provides operations unique to these data types and has a well-documented time complexity (Big O notation).

High performance: because of its memory nature, project maintainers keep complexity to a minimum and an event-based programming model, Redis has excellent performance in read and write operations.

Lightweight without dependencies: written in ANSI C with no external dependencies. Applies to all POSIX environments. Windows is not officially supported, but Microsoft provides an experimental version.

High availability: built-in support for asynchronous, non-blocking, master / slave replication to ensure high availability of data. There is currently a high availability solution called Redis Sentinel that is currently available, but is still considered work in progress.

The above is what Redis refers to all the contents of the database, thank you for reading! I believe we all have a certain understanding, hope to share the content to help you, if you want to learn more knowledge, welcome to follow the industry information channel!
