Summary: Native GeoSpatial Support in Hive
Key: HIVE-26222
URL: https://issues.apache.org/jira/browse/HIVE-26222
Project: Hive
Issue Type: Task
Components: Hive, HiveServer2
Reporter: mahesh kumar behera
Assignee: mahesh kumar behera
This is an epic Jira to support GeoSpatial datatypes natively in Hive. This
will cater to the applications which queries on large volumes of spatial data.
This support will be added in a phased manner. To start with, we are planning
to make use of framework developed by ESRI
([https://github.com/Esri/spatial-framework-for-hadoop).] This project is not
very active and there is no release done to maven central. So its not easy to
get the jars downloaded directly using pom dependency. Also the UDFs are based
on older version of Hive. So we have decided to make a copy of this repo and
maintained it inside Hive. This will make it easier to do any improvement and
manage dependencies. As of now, the data loading is done only on a binary data
type. We need to enhance this to make it more user friendly. In the next
phase, a native Geometry/Geography datatype will be supported. User can
directly create a geometry type and operate on it. Apart from these we can
start adding support for different indices like quad tree, R-tree,
ORC/Parquet/Iceberg support etc.
