Problems solved by technology

[0006] For quadtree or Geohash, the nodes of quadtree are fixed, which is equivalent to determining the capacity of 4 nodes, and the grid is evenly divided, resulting in low index efficiency; while for R tree, when there are many overlapping nodes, indexing is performed randomly , resulting in low index efficiency

Abstract

Embodiments of the present application provide an index tree object creation method and related apparatus. The index tree object creation method includes: determining a service area; setting multiplenode capacities; creating a plurality of index tree objects for the service area according to the capacity of the plurality of nodes respectively; the service area is indexed in the plurality of indextree objects to select a target index tree object. The embodiment of the present application avoids determining the node capacity to cause uniform field lattice separation area, so that the index tree object reaches the optimal state meeting certain conditions, and the times of judging the relationship between the position data and the node when searching the index are judged, thereby improving the index efficiency of the index tree object.

Description

technical field [0001] The present application relates to the technical field of computer processing, and in particular relates to the creation of an index tree object and its indexing method and related devices. Background technique [0002] Spatial indexing, that is, querying spatial data, describes the location information of data stored on a medium, and is used to improve the efficiency of data acquisition by the system, and is also called a spatial access method. [0003] For example, in scenarios such as logistics, the location in the order is usually indexed to the business area of ​​logistics to determine the business operation point that processes the order. [0004] Currently, quadtree index, R-tree index, and Geohash are commonly used spatial index methods. [0005] The quadtree index is similar to the R-tree index, which is equivalent to determining the capacity of 4 nodes, and continuously and evenly divides the area; Geohash also divides the area evenly in the...
