What is spark GraphX used for?
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.

Which big companies use Neo4j?
Neo4j is the leading graph database technology that drives innovation and competitive advantage at Airbus, Comcast, eBay, NASA, UBS and more. Thousands of community deployments and more than 400 customers harness connected data with Neo4j to reveal how people, processes, locations and systems are interrelated.
Is NoSQL a Neo4j?
1. Neo4j : It is most famous graph database management system and it is also NoSQL database system which is developed by Neo4j, Inc. It is different from Mysql or MongoDB as it has its features that makes it special compared to other Database Management System.
Why is Apache Spark GraphX useful for Neo4j?
Integration of Apache Spark GraphX tool with Neo4j database management system could be useful when you work with a huge amount of data with a lot of connections. Neo4j store the information in the graph format which reduces greatly the time which is needed for requests to the database.
Which is better Neo4j or GraphX for realtime processing?
GraphX is more of a realtime processing framework for the data that can be (and it’s is better when) represented in a graph form. With GraphX you can use various algorithms that require large amounts of processing power (both RAM and CPU), and with neo4j you can (reliably) persist and update that data. This is what I’d suggest.
How to load a graph in Apache Spark?
To connect to the Neo4j database, we need to create Neo4j instance: To load graph from the Neo4j database, we should use Cypher, which is Neo4j’s query language. Using the query below, we will obtain the whole graph with all nodes and all edges: Now we can load the graph:
What is the purpose of GraphX in spark?
GraphX: 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.
