Embodiment Construction

[0028] The present invention will be described in further detail in conjunction with the following specific examples and accompanying drawings, and the protection content of the present invention is not limited to the following examples. Without departing from the spirit and scope of the inventive concept, changes and advantages conceivable by those skilled in the art are all included in the present invention, and the appended claims are the protection scope.

[0029] The specific implementation of the present invention is divided into two aspects, one is the storage method of the materialized view, the present invention stores the materialized view on the distributed file system, and organizes the data in a column-based storage manner, so a novel data layout method is proposed; The second is the maintenance method of the materialized view based on this storage structure, that is, the update and maintenance of the view, and the corresponding model is given.

Abstract

The invention belongs to the technical field of databases, in particular discloses a materialized view layout in a distributive system under a column-orientated storage environment and a maintaining method of the materialized view layout. The invention comprises a high-expandability data layout strategy and a method for efficiently maintaining consistency of views. According to the invention, a relational data sheet is stored by using a column-orientated storage model, and the materialized view layout in the distributive system under the column-orientated storage environment is maintained by introducing a consistency model. The invention is suitable for large-scale distributed file systems of the column-orientated storage environment, and provides a data management solution for a data analysis-orientated application.

Description

technical field [0001] The invention belongs to the technical field of databases, and in particular relates to a materialized view layout and maintenance method in a distributed system in a column-based storage environment. Background technique [0002] With the rapid growth of data scale, data-intensive computing is particularly attractive in the current research field. Many large IT companies, such as Google, Amazon, and their competitors are working on building large-scale data analysis platforms to support data-intensive computing. calculate. Here, data-intensive computing systems include obtaining, updating, sharing, archiving data, and providing sufficient computing power on massive data sets. A cluster system consisting of a large number of shared-nothing commodity computers is usually used as the infrastructure to provide these services effectively and efficiently. [0003] Typically, data comes from many sources (eg, operational databases, Web 2.0 web pages, etc.)...
