[DISCUSSION] Geo spatial index algorithm improvement and UDFs enhancement
Now carbondata supports geo spatial index and one query UDF 'InPolygon'.
We plan to optimize the Spatial index feature with three points:
1 reduce the parameters of table properties when creating geo table;
2 add more UDFs and support more complex query scenario;
3 allow user to define the spatial index when 'LOAD' and 'INSERT INTO', and
carbon will still generated the value of spatial index column internally
when user does not give.
I have added an initial v1 design document 'CarbonData Spatial Index Design
Doc.docx' and UDF interface design document 'Carbon Geo UDF Enhancement
Interface Design.docx', please check and give comments/inputs/suggestions.
