TALK 1: User-Defined Function (UDF)
User-Defined Function (UDF) makes Pinot very flexible, but at the cost of worse performance due to the extra row-by-row computation and lack of indexes. Derived Column is introduced to help pre-materialize the UDF computation so that it can achieve the best performance but still maintain great flexibility. Further more, it can be configured and generated on top of the existing data without downtime.
