Abstract

The invention discloses a data storage method and system. The method comprises the steps of acquiring to-be-stored data, dividing the to-be-stored data into data blocks, writing the data blocks into a memory, performing parallel compression processing on the data blocks in the memory to obtain a data compression packet, and writing the data compression packet into a magnetic disk. The data storage method and system increase the speed of writing the data into the magnetic disk.

Description

technical field [0001] The invention relates to the technical field of data storage, in particular to a data storage method and system. Background technique [0002] With the development of Internet technology and the advent of the era of big data, people have more and more demands for data access. In order to improve access speed and reliability, data is usually stored in a cache, specifically distributed to a series of servers. This data storage method is called a distributed cache. [0003] The emergence of distributed cache enables users to read data with high performance, dynamically expand cache nodes, automatically discover and switch fault nodes, automatically balance data partitions, and provide users with a graphical management interface, which is very easy to deploy and maintain. convenient. [0004] Redis is an open-source, network-enabled, in-memory, optional persistent key-value store database written in ANSIC. According to the data of the monthly ranking we...
