Apache Spark is a widely-used open-source distributed computing system that provides a fast and efficient platform for large-scale data processing, orderby pyspark. In PySpark, DataFrames are the primary abstraction for working with structured data. A DataFrame is a distributed collection of data organized into named columns, orderby pyspark to a table in a relational database.

In this article, we will see how to sort the data frame by specified columns in PySpark. We can make use of orderBy and sort to sort the data frame in PySpark. OrderBy function i s used to sort an object by its index value. Return type: Returns a new DataFrame sorted by the specified columns.
