Hi community,
Currently, carbon supports IN_POLYGON and IN_POLYGON_LIST udf's,
where user has to manually provide the polygon points(series of latitude
and longitude pair), to query carbon table based on spatial index.
This feature will support JOIN tables based on IN_POLYGON udf
filter, where polygon data exists in a table.
Please find below link of design doc. Please check and give
your inputs/suggestions.
