The Apache Spark engine is a powerful data processing engine that can handle large-scale data processing tasks. It uses in-memory computing, distributed storage, and fault tolerance to provide fast performance. When an application runs on Spark, the Driver Program divides the data into smaller chunks called Resilient Distributed Datasets (RDDs). These RDDs are distributed across multiple nodes in the cluster, and each node processes its assigned data. Once processing is complete, Spark aggregates the results to produce the final output.
