Explain mappartitions() and mappartitionswithindex()?
Answer Posted / Ravindra Kumar Singh
"mapPartitions()" is a transformational method in Apache Spark that applies a function to each partition of an RDD (Resilient Distributed Dataset). It returns a new RDD with the same number of partitions, but containing transformed data. The "mapPartitionsWithIndex()" method performs the same operation, but also includes the partition index as an additional argument for the user-defined function.n
