Learning Neo4j 3.x - Second Edition

By: Jerome Baton

Overview of this book

Neo4j is a graph database that allows traversing huge amounts of data with ease. This book aims at quickly getting you started with the popular graph database Neo4j. Starting with a brief introduction to graph theory, this book will show you the advantages of using graph databases along with data modeling techniques for graph databases. You'll gain practical hands-on experience with commonly used and lesser known features for updating graph store with Neo4j's Cypher query language. Furthermore, you'll also learn to create awesome procedures using APOC and extend Neo4j's functionality, enabling integration, algorithmic analysis, and other advanced spatial operation capabilities on data. Through the course of the book you will come across implementation examples on the latest updates in Neo4j, such as in-graph indexes, scaling, performance improvements, visualization, data refactoring techniques, security enhancements, and much more. By the end of the book, you'll have gained the skills to design and implement modern spatial applications, from graphing data to unraveling business capabilities with the help of real-world use cases.

Preface

Summary


We have seen how to check whether our queries are wasting resources and how to correct them, because CPU cycles are time and electric power, and your time is precious! Notwithstanding the fact that it generates heat and the climate is already a mess.

We saw Neo4j's execution plans, how to read them, and spot what may be an issue. We saw what the parameters are and how they might remind you of JDBC's PreparedStatements. We saw how to force the use of indexes or labels (you may have to do a comparison of the performances of both, depending on your graph and queries). Remember this old saying that elders transmit to younger disciples of our profession: Make it work, then, and only then, optimize!

Now, let's switch to something totally different: Chapter 8, Importing data into Neo4j.

The import queries can be profiled too!
