Abstract

The invention provides a data indexing method for streaming time sequence data, which comprises the following steps of: 1, establishing an integral data indexing structure which is formed by adding aB * tree pointing to a sibling pointer to non-root and non-leaf nodes of a B + tree; Step 2, carrying out batch resource application and index optimization; And step 3, carrying out trigger type treestructure segmentation and combination.

Description

technical field [0001] The invention relates to a data indexing method, and mainly relates to a data indexing method for streaming time series data. Background technique [0002] With the rapid development and wide application of cutting-edge Internet technologies such as virtualization and cloud computing, a large number of mobile portable terminals and sensor devices are deployed in every corner of the world, playing the role of information collection and acquisition. Especially in recent years, the concept of "Internet of Things" advocating the Internet of Everything has been proposed. Mobile sensor networks connected to each other through real-time networks have been widely used in military, economic, medical and other fields, and have achieved considerable practical value. However, with the acquisition and processing of massive streaming time-series data information, although on the one hand, the scale of data has been expanded, which is conducive to the monitoring and ...
