Abstract

The embodiment of the invention provides a data query method and device, a data display method and device, electronic equipment and a storage medium, and relates to the technical field of maps. The method comprises the following steps: receiving a query request, and determining at least one latitude and longitude coordinate to be queried according to the query request; determining a target grid identifier of a grid where the latitude and longitude coordinates are located; querying a target fence identifier corresponding to the target grid identifier in pre-established grid fence index information; the grid fence index information comprises at least one key-value pair, a key in the key-value pair is a grid identifier of a grid, and a value is related to a fence identifier of a geofence having a coverage relationship with the grid. According to the embodiment of the invention, the time complexity of query is reduced from O (logn) to O (1) when an Rtree scheme is used, the query efficiency is greatly improved under the scene of ten-million-level data volume and 10wqps-level request volume, and millisecond-level data requests and real-time data statistics requirements are supported.

Description

technical field [0001] The present application relates to the field of map technology, and in particular, to a data query method, display method, apparatus, electronic device, computer-readable storage medium, and computer program product. Background technique [0002] Geographical location is the most important user information. Products related to maps are the most frequent services in people's lives. With the rapid development of map and geographic information technology, all aspects of people's life, from business and social search, from travel route design to food and shopping choices, from aerial photography to animal migration, are inseparable from maps and geographic information. [0003] The time complexity of related technologies to obtain geographic information is O(logn). Although there are relatively mature middleware (MySQL, PostgreSQL), the disk storage and performance throughput can cope with the order of 10wqps online in large-scale fence and high-traffic s...
