The grouping allows pandas to perform vectorized operations and will be faster than normal udf. for normal case like a*b, a normal spark udf will suffice and be faster.</P><P></P><P><A href="https://bryancutler.github.io/vectorizedUDFs/" target="test_blank">https://bryancutler.github.io/vectorizedUDFs/</A></P> Mon, 02 Jan 2023 14:17:25 GMT https://community.databricks.com/t5/data-engineering/benefit-of-using-vectorized-pandas-udfs-instead-of-the-standard/m-p/14438#M8926 ramravi 2023-01-02T14:17:25Z https://community.databricks.com/t5/data-engineering/benefit-of-using-vectorized-pandas-udfs-instead-of-the-standard/m-p/44237#M27623 <OL><LI>Vectorized Pandas UDFs offer improved performance compared to standard PySpark UDFs by leveraging the power of Pandas and operating on entire columns of data at once, rather than row by row.</LI><LI>They provide a more intuitive and familiar programming interface for data manipulation and transformation, as they allow you to use Pandas functions and syntax directly.</LI><LI>Vectorized Pandas UDFs enable seamless integration with existing Pandas code, making it easier to reuse and adapt code from other Python data analysis workflows.</LI></OL> Sun, 10 Sep 2023 19:55:03 GMT https://community.databricks.com/t5/data-engineering/benefit-of-using-vectorized-pandas-udfs-instead-of-the-standard/m-p/44237#M27623 Sai1098 2023-09-10T19:55:03Z
