Question 125

Which of the following types of processes induces a stage boundary?

    Correct Answer: A

    A stage boundary in distributed computing environments, like Apache Spark, is induced when a shuffle occurs. A shuffle process requires data to be redistributed across different physical nodes or executors. This effectively splits the process into stages as data needs to be reorganized before the next set of operations can be performed.
