For example, in line #86 I checked if the group by result is null. Perhaps I miss something in the general null handling strategy in agg functions. ########## File path: pinot-core/src/main/java/org/apache/pinot/core/query/aggregation/function/StUnionAggregationFunction.java ########## @@ -0,0 +1,137 @@ +/** + * Licensed to the Apache Software Foundation (ASF) under one + * or more contributor license agreements.
