RDD Operations and Core AbstractionsSpark applications manipulate data through Resilient Distributed Datasets (RDDs), which serve as the foundational data structure. A typical word count operation demonstrates the transformation pipeline:val textFile = sparkContext.textFile("hdfs://cluster/data/inpu...

Checkpointing materializes critical intermediate results to a fault-toleratn store and cuts off lineage, preventing expensive re-computation across deep DAGs when failures occur. Caching (or persisting) keeps data in memory/disk for faster reuse but retains dependencies, so data loss may still trigg...
