Extending Cypher

Now that we have seen Cypher and the famous APOC project, we will talk about adding functions and procedures to a Neo4j instance, just like writing your own APOC for your projects, except that your extensions are more directly related to your business.  

In this chapter, we will cover the following topics:

  • Building an extension project (plugin)
  • User-defined functions 
  • User-defined procedures
  • Custom aggregators
  • Unmanaged extensions
  • Streaming JSON responses

Let's empower ourselves with more knowledge.
