Problems solved by technology

However, it needs to rely on the efficiency of reading, writing and storage of the storage server. For large-scale data, the requirements of the storage server are also increased accordingly. Multiple server data nodes mean that data must be stored on multiple storage servers. The disk size of the storage server and Reading and writing data will reduce the reading efficiency of the storage server

Abstract

The invention belongs to the technical field of data storage, and provides a clustered database distributed storage method and device. The method comprises the following steps: receiving data processing request information, wherein the processing request information comprises keywords of data to be processed; inquiring whether the data to be processed exists in a cache of a storage server or not according to the keywords; and if the data to be processed does not exist, inquiring whether the data to be processed exists in node databases of the storage server or not, and if so, processing the data to be processed, and feeding a processing result back to the cache of the storage server in order that the cache of the storage server transmits the processing result to a client. Through adoption of the method and the device, the data reading efficiency of the storage server is increased.

Description

technical field [0001] The invention belongs to the technical field of data storage, and in particular relates to a method and a device for distributed storage of a cluster database. Background technique [0002] Traditional network storage systems use centralized storage servers to store all data. Storage servers become the bottleneck of system performance and the focus of reliability and security, which cannot meet the needs of large-scale storage applications. [0003] The current distributed storage system is to disperse and store data on multiple independent devices. Using a scalable system structure, using multiple storage servers to share the storage load, and using the location server to locate and store information, this solution alleviates the pressure on a single storage server to a certain extent, and improves the reliability, availability and access of the system Efficient and easy to expand. However, it needs to rely on the efficiency of reading, writing and ...
