Spark GraphX

About Spark GraphX

Apache Spark's API for graphs and graph-parallel computation. GraphX extends the Spark RDD with a graph abstraction, providing a set of fundamental operators and optimized algorithms for graph analytics like PageRank and connected components.

Key Features

• 1Distributed graph processing API built into Apache Spark
• 2Property graph model with vertex and edge attributes as RDDs
• 3Pregel API for iterative graph algorithms (PageRank, connected components)
• 4Graph operators: subgraph, joinVertices, aggregateMessages
• 5Integrates with Spark's DataFrame API and MLlib for graph ML workflows

How Python Data Engineers Use Spark GraphX

Python data engineers work with Spark GraphX indirectly via PySpark's `graphframes` library, which wraps GraphX with a DataFrame-based API. Engineers use GraphFrames to compute network metrics — PageRank, shortest paths, triangle counts — on large graphs stored as edge and vertex DataFrames in a Spark data lake pipeline.
