Graph Data Processing with Cypher

By: Ravindranatha Anthapu

Overview of this book

While it is easy to learn and understand the Cypher declarative language for querying graph databases, it can be very difficult to master it. As graph databases are becoming more mainstream, there is a dearth of content and guidance for developers to leverage database capabilities fully. This book fills the information gap by describing graph traversal patterns in a simple and readable way. This book provides a guided tour of Cypher from understanding the syntax, building a graph data model, and loading the data into graphs to building queries and profiling the queries for best performance. It introduces APOC utilities that can augment Cypher queries to build complex queries. You’ll also be introduced to visualization tools such as Bloom to get the most out of the graph when presenting the results to the end users. After having worked through this book, you’ll have become a seasoned Cypher query developer with a good understanding of the query language and how to use it for the best performance.

Using APOC Utilities

APOC is an acronym for Awesome Procedures On Cypher. It is an add-on library for Neo4j that provides a lot of procedures and functions that can extend Cypher to perform more complex operations. It’s built and maintained by Neo4j Labs. This chapter talks about using APOC utilities to extend the built-in capabilities of Cypher. It gives you more options to load CSV and JSON data, schedule timers, carry out ad hoc batch data modifications, and more.

We will cover these topics in this chapter:

  • Installing APOC
  • Working with data import and export
  • Viewing database schema
  • Executing dynamic Cypher
  • Working with advanced path finding
  • Connecting to other databases
  • Using other useful methods

We will start with APOC plugin installation. We will take a look at the Neo4j Desktop plugin installation as well as installation on a server.
