Resilient Distributed Datasets (RDDs) are a fundamental data structure in PySpark, which is an open-source distributed computing framework for big data processing. RDDs are immutable distributed collections of objects that can be processed in parallel across multiple nodes in a cluster. RDDs are fault-tolerant, meaning they can recover from node failures and ensure data consistency.
