Method and apparatus for data access in distributed caching system

Abstract

The invention discloses a method for data access in a distributed caching system, which comprises: server nodes receiving a data access request from a client, determining astorage schema of the accessing data according to the data access request accessing the data according to the storage schema and returning an accessing result to the client. The invention also discloses a data accessing apparatus for the data access in the distributed caching system, which improves the efficiency of data access and price-performance ratio of the distributed caching system.

Description

technical field [0001] The invention relates to the field of distributed cache, in particular to a method and device for data access 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 node is responsible for data storage, and the client can read, update, and delete ...

Problems solved by technology

[0005] Option 1, using all memory in the distributed cache system to store large amounts of data can ensure access efficiency, but this requires a high economic cost, and can only be used in some very important or projects that can create high economic value It is difficult to apply in ordinary projects;

[0006] Option 2, using the combination of memory and hard disk to store data, all data is stored on the hard disk, when reading data, the data is read from the hard disk and cached in the memory, the main disadvantage of this method is that some require more Data with high access efficiency also needs to be read from the hard disk first, cached in memory, and share a data storage method with ordinary data. Data access can only obtain ordinary access efficiency, resulting in low access efficiency
