Bryan Cafferky teaches how to write and optimize PySpark pandas user-defined functions for parallel execution in Databricks.

PySpark pandas user defined functions are custom code you can run in parallel over the cluster nodes getting top performance. Spark 3.0 launched a new way to code traditional Python User Defined Functions (UDF) (introduced in video 26). This video teaches you how to code the new PySpark pandas user defined functions.
