Sergey Shelukhin commented on HIVE-15857:
-----------------------------------------
+1 w/one small comment. There is some repetitive code that is handled less
repetitively elsewhere in vectorization iirc (e.g. selectedInUse where it does
int index = sIU ? sel[i] : i, instead of having 2 separate loops). I am
assuming this is due to vectorization requirements that they are all handled
separately :)
> Vectorization: Add string conversion case for UDFToInteger, etc
