I think the LASTWITHTIME udf was added recently and is not part of the 0.9.3.. I might be wrong

Hi @Kishore G the docs mention LASTWITHTIME in

0.9.0

. Could there have been extra functionality that is required for it added later maybe?

If I understand this correctly, it looks like the lastwithtime udf simply wasn’t added to the transform function type enum https://github.com/apache/pinot/blob/master/pinot-common%2Fsrc%2Fmain%2Fjava%2Forg%2Fapache%2Fpinot%2Fcommon%2Ffunction%2FTransformFunctionType.java
