Spark Programming in Python for Beginners with Apache Spark 3 - Aggregating Dataframes

The video tutorial covers the concept of aggregations in Apache Spark, focusing on three main types: simple, grouping, and windowing aggregations. It explains how these aggregations are implemented using built-in functions in Spark, such as average, count, max, min, and sum. The tutorial provides examples of simple aggregations, like summarizing a data frame, and grouping aggregations using SQL expressions and data frame methods. An exercise is given to practice creating a data frame with specific aggregations, and the video concludes with a preview of windowing aggregates.
