What is flatmap in pyspark?

Question Posted / Jai Kant Rangila

Answer Posted / Jai Kant Rangila

FlatMap in PySpark is a transformation operation that applies a user-defined function to each element of an RDD (Resilient Distributed Dataset) and then flattens the result. It's useful for breaking up complex data structures, such as lists or tuples, into individual elements.
