Resilient Distributed Datasets (RDDs)
Save
Resilient Distributed Datasets (RDDs) are a fundamental concept in Apache Spark, a popular big data processing framework. RDDs represent immutable, partitioned collections of data elements that can be distributed across a cluster of computers and processed in parallel. They provide a fault-tolerant and efficient way to handle large datasets and support a wide range of data processing operations.
Understanding RDDs
An RDD is a distributed collection of data partitioned into smaller logical units called partitions. Each partition is processed independently on different nodes in the cluster, allowing for parallelization and scalability. RDDs are immutable, meaning they cannot be modified once created. Instead, new RDDs are created as transformations are applied to existing RDDs.
