Azure Data Explorer extends functionality to support geospatial joins
发布日期：九月 29, 2020
Azure Data Explorer has supported geospatial functions since 2019.
The query pattern of geospatial joins is oftentimes used in various mobility solutions (geospatial telemetry and static reference data), geospatial risk analysis and agriculture optimization using weather data. It consists of a coarse-grained join using the S2 cell coverage provided by geo_polygon_to_s2cells and the later exact validation using the geo_point_in_polygon function.
