spark sql geospatial

Escrito por em 17/10/2020


The lack of spatial join implementations in open source geospatial analytics libraries is one of the biggest impediments to leveraging geospatial context for rich predictive analytics, and our goal in this talk is to show how we are solving this problem using Magellan and Spark. Big data solutions are designed to handle data that is too large or complex for traditional databases. Enjoy your stay :).

Big data processing is hard and complex, Apache Spark hides most of that complexity away. A Principal Data Analytics Consultant with experience in delivering Microsoft Azure/ SQL Data Analytics solutions. { "name" : "San Francisco Intl", "type" : "International", "code" : "SFO" }
