   What is Apache Spark Core?

   • Spark Core is the heart of Apache Spark and it is responsible for providing distributed task transmission, scheduling, and I/O functionality. The Spark Core engine uses the concept of a Resilient Distributed Dataset (RDD) as its basic data type. The RDD is designed so it will hide most of the computational complexity from its users.

   • Resilient Distributed Dataset (RDD) Resilient Distributed Datasets (RDDs) are fault-tolerant collections of elements that can be distributed among multiple nodes in a cluster and worked on in parallel.
   • Directed Acyclic Graph (DAG) As opposed to the two-stage execution process in MapReduce, Spark creates a Directed Acyclic Graph (DAG) to schedule tasks and the orchestration of worker nodes across the cluster.
   • DataFrames and Datasets. In addition to RDDs, Spark handles two other data types: DataFrames and Datasets. DataFrames are the most common structured application programming interfaces (APIs) and represent a table of data with rows and columns.
   • Spark Core. Spark Core is the base for all parallel data processing and handles scheduling, optimization, RDD, and data abstraction. Spark Core provides the functional foundation for the Spark libraries, Spark SQL, Spark Streaming, the MLlib machine learning library, and GraphX graph data processing.
