Questions tagged [neo4j-apoc]

APOC is short for "Awesome Procedures on Cypher." Introduced in Neo4j release 3.0, APOCs are callable procedures which extend the Cypher query language.Questions with the neo4j-apoc tag should be for "small, generic helper functions for common tasks" that are not available in the Cypher query language.

APOC procedures are "User Defined Procedures." They are similar to stored procedures in some relational databases. APOCs can be written in any language that runs on the JVM. Questions tagged with neo4j-apoc should have an accompanying tag for the specific language being used.

Built in procedures are included in Neo4j releases. Before posting a question on StackOverflow, please consult the Neo4j documentation and ask if your task is possible in the public chat channels.
