PySpark: Dataframe Sort Within Partitions

This tutorial will explain with examples on how to sort data within partitions based on specified column(s) in a dataframe.

Single Column Ascending Order: Using single column to sort data within partitions of a dataframe in an ascending order.
Single Column Descending Order: Using single column to sort data within partitions of a dataframe a descending order.
Single Column Ascending Order nulls first: Using single column to sort data within partitions of a dataframe an ascending order with nulls at the beginning.
Single Column Ascending Order nulls last: Using single column to sort data within partitions of a dataframe an ascending order with nulls at the end.
Single Column Descending Order nulls first: Using single column to sort data within partitions of a dataframe a descending order with nulls at the beginning.
Single Column Descending Order nulls last: Using single column to sort data within partitions of a dataframe a descending order with nulls at the end.
Multiple Columns Ascending Order: Using multi columns "db_name","db_id" to sort data within partitions of a dataframe an ascending order.
Multiple Columns Descending Order: Using multiple columns to sort data within partitions of a dataframe a descending order.
Multiple Columns Ascending/Descending(mix) Order: Using multiple columns to sort data within partitions of a dataframe a descending or an ascending order.
Multiple Columns Ascending/Descending Order nulls first/last: Using single column to sort data within partitions of a dataframe a descending order with nulls at the beginning.
