pandas user-defined functions | Databricks on AWS

July 14, 2020. A pandas user-defined function (UDF)also known as vectorized UDFis a user-defined function that uses Apache Arrow to transfer data and pandas to work with the data. pandas UDFs allow vectorized operations that can increase performance up to 100x compared to row-at-a-time Python UDFs. For background information, see the blog post New Pandas UDFs and Python Type Hints in the Upcoming Release of Apache Spark 3.0 and Optimize conversion between PySpark and pandas Working with Time Series | Python Data Science HandbookTo make the creation of regular date sequences more convenient, Pandas offers a few functions for this purpose: pd.date_range() for timestamps, pd.period_range() for periods, and pd.timedelta_range() Visualization pandas 0.25.0.dev0+752.g49f33f0d For pie plots its best to use square figures, i.e. a figure aspect ratio 1. You can create the figure with equal width and height, or force the aspect ratio to be equal after plotting by calling ax.set_aspect('equal') on the returned axes object.. Note that pie plot with DataFrame requires that you either specify a target column by the y argument or subplots=True.
