Abstract

The invention relates to the field of trajectory data processing, and discloses a spatio-temporal trajectory indexing and query processing method, device, equipment and medium. According to a received trajectory query instruction, it is determined that the trajectory query instruction belongs to ID time range query, spatio-temporal range query, spatio-temporal similarity query or KNN query; according to the method, comprehensive data processing is carried out on rich queries, multi-element query types are planned as a whole, complex upper-layer applications are supported, a uniform spatial-temporal trajectory index and query processing framework which can compress data, is light and efficiently supports the query types is designed, diversified query requirements are met, and the query efficiency is improved. The technical problem of optimal management of the spatio-temporal trajectory data is solved.

Description

technical field [0001] The present application relates to the field of trajectory data processing, in particular to a spatio-temporal trajectory index and query processing method, device, equipment and medium. Background technique [0002] In real life and practical applications, many types of trajectory data such as AIS ship data, animal migration trajectories, and typhoon movement trajectories are carried out in free space. The above types of trajectories are well described by sequence models. With the development of spatio-temporal big data computing, the data scale is increasing exponentially. Traditional methods face multiple challenges such as high storage pressure, complex management, and high computing diversity. For large-scale spatio-temporal trajectory data and complex and diverse query processing scenarios, manual management And system tuning seems stretched. [0003] Therefore, how to meet the diverse query requirements and realize the optimal management of sp...
