Detailed explanation-1: -Which of the following statements are true in the context of Apache Spark GraphX operators ? S1: Property operators modify the vertex or edge properties using a user defined map function and produces a new graph.
Detailed explanation-2: -GraphX is Apache Spark’s API for graphs and graph-parallel computation. GraphX unifies ETL (Extract, Transform & Load) process, exploratory analysis and iterative graph computation within a single system.
Detailed explanation-3: -GraphX is a new component in Spark for graphs and graph-parallel computation. At a high level, GraphX extends the Spark RDD by introducing a new Graph abstraction: a directed multigraph with properties attached to each vertex and edge.
