Demystifying Neo4j With APOC and Java
summary
Shows how to add extended APOC JAR and enable JSON import/export via apoc.config, and wires Neo4j into Java with a wrapper class and a GET controller; demonstrates the difference between apoc.do.when vs apoc.when (do runs writes so breaks readOnly transactions), fixes a transactional error by removing the write variant, and profiles a query where switching to apoc.search.node cuts DB hits from 19 to 2. Advises avoiding APOC for trivial create/delete cases due to overhead.
