Description
I would like to propose to incorporate a newly developed spatial querying component into Hive.
We have recently developed a high performance MapReduce based spatial querying system Hadoop-GIS, to support large scale spatial queries and analytics.
Hadoop-GIS is a scalable and high performance spatial data warehousing system for running large scale spatial queries on Hadoop. Hadoop-GIS supports multiple types of spatial queries on MapReduce through space partitioning, customizable spatial query engine RESQUE, implicit parallel spatial query execution on MapReduce, and effective methods for amending query results through handling boundary objects on MapReduce. Hadoop-GIS takes advantage of global partition indexing and customizable on demand local spatial indexing to achieve efficient query processing. Hadoop-GIS is integrated into Hive to support declarative spatial queries with an integrated architecture.
We have an alpha release. We look forward to contributors in Hive community to contribute to the system.
