Example Embodiment

[0039] The present invention will be further described in detail below in conjunction with the drawings.

[0040] figure 1 It is a schematic structural diagram of a data processing system according to an embodiment of the present invention. Such as figure 1 As shown, the data processing system includes multiple storage nodes. The multiple storage nodes may be divided into multiple levels, for example, including at least a first-level storage node 20A and a second-level storage node 20B. Each level of storage node may include one or more storage nodes.

[0041] The data processing system also includes a data distribution device 40, which is used to classify the data stored in each storage node according to the data classification rules, so as to obtain data of different levels. Data can be divided into first-level data, second-level data, third-level data, and so on.

[0042] For the data stored in each storage node, if the data stored in a storage node is classified into first-lev...

Abstract

The invention discloses a data distribution device which comprises a data classification unit and a data migration unit, wherein the data classification unit is used for classifying data stored in a plurality of storage nodes of a data processing system to obtain data of various stages according to a set data classification rule, wherein the data of various stages at least comprise first stage data and second stage data, the plurality of storage nodes at least comprise a first stage storage node and a second storage node; and the data migration unit is used for migrating the first stage data to the first storage node when the first stage data are not stored in the first storage node of the plurality of storage nodes as well as migrating the second stage data to the second storage node when the second stage data are not stored in the second storage node of the plurality of storage nodes. The invention also discloses a data processing method and system. Therefore, the efficiency of accessing data from mass data is improved.

Description

technical field [0001] The present invention relates to the technical field of computer data processing, and more specifically, to a data processing system, a data processing method, and a data distribution device in a large-scale data environment. Background technique [0002] The typical hierarchical storage strategy adopted by the existing storage system is to store frequently accessed data in the memory, and use different cache replacement algorithms to update the data stored in the memory. are stored on disk. This facilitates quick positioning during data query and analysis, thereby reducing maintenance and processing overhead. [0003] In addition, many existing distributed storage systems distribute and store massive data on multiple storage nodes according to a certain distribution strategy. However, as the amount of data increases and the number of nodes remains unchanged, memory will become a bigger bottleneck, and the overhead of data location will also increase...
