Data writing and reading method and device in distributed caching system

Abstract

The invention discloses data writing and reading method and device in a distributed caching system. According to the distributed caching system, the indexing information of the data is stored in an internal memory, and the data information is stored in a hard disk; and when the writing and reading of the data are carried out, corresponding operation be performed on the hard disk through the indexing information stored in the internal memory. According to the method and device provided by the embodiment of the invention, the data is written and read in combination of the internal memory and the hard disk, and the internal memory is only used for storing indexing information; the reading and writing of the data are carried out in combination of the internal memory and the hard disk, so that the problem that all data is stored into the internal memory can be avoided, and the requirements on caching of a large number of data can be met; and furthermore, the data read-write efficiency can be improved by reading and writing the data in the combination of the internal memory and the hard disk, so the reliability of the system can be improved.

Description

technical field [0001] The invention relates to the technical field of cloud computing, in particular to a method and device for writing and reading data in a distributed cache system. Background technique [0002] Cloud Computing is Grid Computing, Distributed Computing, Parallel Computing, Utility Computing, Network Storage Technologies, Virtualization , Load Balance (Load Balance) and other traditional computer technology and network technology development fusion product. It aims to integrate multiple relatively low-cost computing entities into a system with powerful computing capabilities through the network. Distributed cache is a field in the field of cloud computing. Its role is to provide distributed storage services for massive data and high-speed read and write access capabilities. [0003] The distributed cache system is composed of several server nodes and clients connected to each other. The server nodes are responsible for data storage, and the clients can pe...
