ST_Difference function crashes while working on some geometries about sedona HOT 3 OPEN

@ruanqizhen The polygon is invalid for Difference operation because it has nested holes

You can use ST_ExteriorRing (https://sedona.apache.org/1.5.1/api/sql/Function/#st_exteriorring) to only use the exterior ring.

Hi Jia, thank you for the information.
I need to keep the nested holes, is there a way to process "difference" operation with the nested holes?

@ruanqizhen I don't think it is possible to process the difference function with that. You have to use the exterior ring or take those nested holes out as the individual polygons
