[GitHub] [pinot] walterddr opened a new issue, #10782: [multistage] group-by after left-join causes NPE
walterddr opened a new issue, #10782:
URL: https://github.com/apache/pinot/issues/10782
several issues with handling null in group-by, (typical scenario: group-by is applied after left-join)
the problems are:
1. when the nullable column is in the group-key. the group-set aggregation causes the results (or error) to not populated through.
2. when the nullable column is in the agg function. it simply throws NPE
the problem might also happen to other operators that doesn't handle null arguments
