When creating an RDD, what goes on internally?

Question Posted / Manjeet Singh

Answer Posted / Manjeet Singh

"When creating an RDD in Apache Spark, the driver program creates a logical directed acyclic graph (DAG) of computations. Each node in the DAG represents a transformation or action on the data, while edges indicate the dependencies between them. The RDD lineage is maintained to track each RDD's creation and all its transformations."
