Non-scalar UDFs includepandas_udf,mapInPandas,mapInArrow,applyInPandas. Pandas UDFs use Apache Arrow to transfer data and pandas to work with the data. Pandas UDFs support vectorized operations that can vastly increase performance over row-by-row scalar UDFs. ...
Photon is developed in C++ to take advantage of modern hardware, and uses the latest techniques in vectorized query processing to capitalize on data- and instruction-level parallelism in CPUs, enhancing performance on real-world data and applications—all natively on your data lake....
