Apache Spark - Architecture and Components
Introduction This note will look at a high-level of Spark architecture and understand how it execute actions across notes
Apache Spark - Caching and Persistance
Introduction If we call actions in an RDD for many times and do it naively, the RDDs and all of its dependencies are recomputed at each time we call the action, which can be very expensive, especially for some iterative algorithms.
Apache Spark - Actions and aspects of RDD
Introduction Actions are the operations which will return a final value to the driver program or persist data to an external storage system. It will force the evaluation of the transformations required for the RDD they were called on.
Apache Spark - Set Operations
Introduction This blog post will focus on one type of RDD transformations: Set Operations
Apache Spark - RDD, and fliter & map Transformations
