Azure Cosmos DB: Expanded geospatial support, including automatic indexing of Polygon and LineString objects
28 октября 2016 г.
With the latest service update, Azure Cosmos DB can automatically detect GeoJSON fragments that contain Polygon and LineString objects within your documents, and index them for efficient spatial proximity queries. Spatial querying of Polygon and LineString objects is commonly used to detect "geo-fences" in IoT, telematics, gaming, and mobile applications. You can enable or disable spatial indexing by changing the indexing policy on a per-collection basis.
