Problems solved by technology

In cloud computing, especially in the case of massive data, doing so will cause a huge waste of system resources and consume a lot of time. This is obviously not a suitable way to put it into a real production environment

Embodiment Construction

[0021] Embodiment of the present invention is described below in conjunction with accompanying drawing:

[0022] A kind of cloud computing system with data cube storage index structure of the present invention, figure 1 It stores the index structure for the data cube, which is composed of global data table 1 and index plane 2. In the global data table 1, the x-axis direction represents different keyword fields 3, and the y-axis direction represents different data records 4. Data records and keywords The combination of fields constitutes the corresponding relationship between different data records and their key field contents. Different key fields form different index planes, and each index plane is an index table based on a B+ tree for a certain field.

[0023] A kind of cloud computing system with data cube storage index structure of the present invention, described index table is set up as follows:

[0024] like figure 2 The B+ tree index table shown: When the index is e...

Abstract

The invention discloses a cloud computing system with a data cube storage index structure, which includes one or more management nodes and one or more computing and storage nodes (data nodes). A data cube index structure is established and applied in the system in a distributed manner during data creation and inquiry; one or more keyword fields are set for standardized data during data creation and storage; indexes for the different keyword fields are respectively created; an independent B+ tree structure is generated from each index; and all the B+ tree structures are stacked and form the complete data cube structure with a global data table. Through the data cube storage index structure, accurate retrieval of positioning data in a mass data cloud computing system can be conveniently and rapidly achieved.

Description

technical field [0001] The invention relates to the technical field of electronic information, in particular to a cloud computing system with a data cube storage index structure. Background technique [0002] Explosive data growth has led to multiple problems such as difficult data storage, complex retrieval, and reduced reliability. The emergence of cloud computing and cloud storage technology provides an effective solution for the processing and storage of massive data. [0003] In common cloud computing solutions, HDFS (a distributed file system) of Hadoop (a distributed system infrastructure) can easily realize massive data storage, and at the same time effectively prevent single point of failure and avoid unnecessary losses . However, when performing data retrieval on HDFS, a common method is to enable global search MapReduce (large-scale data parallel computing), which requires a complete filter of all data stored on HDFS. In cloud computing, especially in the case ...
