Apache Spark 3 for Data Engineering and Analytics with Python - Distinct and Filter Transformations

The video tutorial covers RDD transformations in Spark, focusing on the distinct and filter functions. It explains how to remove duplicates using the distinct function and highlights the immutability of RDDs, emphasizing the need to create new RDDs for transformations. The tutorial also demonstrates the use of the filter transformation with a custom function to filter words starting with a specific letter. The importance of using Lambda functions in filtering is discussed, and the tutorial concludes with a summary of key points.
