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 Neo4j extensions

While Cypher is a very powerful language for expressing graph traversal in a simple manner, it is difficult to implement complex graph analytics or handle different kinds of data effectively. This is where Neo4j extensions come into the picture. Neo4j provides the ability to build and register plugins with procedures that can be invoked from Cypher to perform more complex operations.

In the following screenshot, we can see the plugins available to install for the selected database in Neo4j Desktop:

Let’s review what these plugins provide in the following list:

  • APOC: APOC is short for Awesome Procedures On Cypher and is an add-on library that provides a lot of functions and procedures that add useful functionality to Cypher. We discussed the important features of this extension in detail in Chapter 10, Using APOC Utilities.
