PySpark and AWS: Master Big Data with PySpark and AWS - RDD (Partition)

The video tutorial covers the concepts of repartition and collapse transformations in Spark RDDs. It explains how repartitioning can increase or decrease the number of partitions to optimize parallel processing, while collapse is used solely for decreasing partitions. The tutorial includes practical examples demonstrating these transformations and discusses the importance of lazy evaluation in Spark. Additionally, it provides guidance on reading data from directories and highlights the impact of partitioning on performance.

What are the potential drawbacks of increasing the number of partitions?

How does repartitioning affect the distribution of data across partitions?

What is the expected output when saving data from an RDD with multiple partitions?

In what scenarios would you prefer to use collapse over repartition?
