Panel Data Fusion of Distributed Multi-Dimensional Data Index Strategy in Cloud Computing Environment

Abstract

Aiming at the problem that the data index of the distributed storage system in the cloud computing environment does not support complex queries, a multi-dimensional data indexing mechanism, M-Index, is proposed, which uses pyramid technology to describe the multi-dimensional metadata of the data as a one-dimensional index. This is the first time on this basis. The concept of prefix binary tree is proposed, and one-dimensional index and the prefix of PBT effective node are extracted as the primary key of data in the storage system. This paper proposes a new multi-dimensional cloud data indexing scheme based on UB tree: Cloud UB. This scheme first uses the Z curve to reduce the dimensionality of the multi-dimensional space, and then divides the multi-dimensional space into Z regions along the Z curve.
