Editor to share with you what the slicing technology of Redis is, I believe 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 know it!

What do you mean by redis fragmentation?

The sharding (Sharding or Partitioning) technology of Redis refers to the method of distributing data among multiple Redis instances. After sharding, each redis has a subset of the original data set. (recommended: "redis Video tutorial")

When the amount of data is very large, this technology can distribute the amount of data to the redis instances of several hosts, thus reducing the pressure on a single redis instance. Sharding technology can use the storage capacity of multiple computers (in this case, the storage capacity of memory) and computing power in a more scalable way:

(1) from the point of view of storage capacity, sharding technology undertakes more data by using the memory of multiple computers. If there is no sharding technology, the storage capacity of redis will be limited by the memory size of a single host.

(2) from the point of view of computing power, slicing technology can make full use of the computing power of multi-core and multi-hosts by distributing computing tasks to multi-cores or multiple hosts.

The above is all the content of what is the slicing technology of Redis. 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!
