Indexed nearest neighbour search is coming to CartoDB, thanks to an investment in PostGIS 2.0, allowing users to find the nearest N things to anywhere on the planet at ultra-fast speeds. This new functionality enables classic user-friendly queries like "where are the nearest sushi restaurants?" or "how close are Puma Concolor sightings?", and will be rolled out to all CartoDB users over the next few weeks. The development team, led by Paul Oleg and Teodor, is proud of this investment in PostGIS 2.0, which enables fast and efficient nearest neighbor searches.
