Redis geospatial
Introduction to the Redis Geospatial data type
Redis geospatial indexes let you store coordinates and search for them. This data structure is useful for finding nearby points within a given radius or bounding box.
Basic commands
GEOADD
adds a location to a given geospatial index (note that longitude comes before latitude with this command).GEOSEARCH
returns locations with a given radius or a bounding box.
See the complete list of geospatial index commands.
Examples

Add several locations to a geospatial index:
Find all locations within a 5 kilometer radius of a given location, and return the distance to each location:
