Abstract

The embodiment of the invention provides a distributed cache method and system. The method comprises the following step: determining a first cache node according to a primary key value of metadata, and determining a second cache node according to a secondary key value of the metadatathe; and storing metadata issued by center storage node in the first cache node and storing index position of the metadata in the second cache node, wherein the index position of the metadata is used for indicating addresses of the first cache node. According to the invention, the access of the metadata can be achieved by the index position of the metadata, so that the same metadate stored in a plurality of cache nodes is avoided, thereby avoiding redundant storage of the metadata, saving storage space and ensuring the data access consistency.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of communications, and more specifically, to a distributed caching method and system. Background technique [0002] The data processed by modern application systems is growing rapidly, and a large amount of centralized data processing is evolving to distributed processing. In a distributed system, the data is distributed and stored on multiple nodes, and the storage and computing capabilities are expanded by adding nodes. However, multi-node storage of data needs to solve the problem of data consistency on each node. The problem of consistency is to solve the synchronization between multiple copies. For example, a system that requires read and write operations on multiple replica nodes requires distributed locks or global locks to achieve data update consistency, which greatly affects system real-time performance and performance, and increases system complexity. [0003] In the di...
