MikeThomsen commented on issue #2956: NIFI-5537 Create Neo4J cypher execution processor URL: https://github.com/apache/nifi/pull/2956#issuecomment-451783633 @mans2singh The OpenCypher team released a Neo4J-style driver that uses Gremlin behind the scenes. It appears to be API-compatible with the official Neo4J driver. What we'd probably want to do first is look at both drivers and see if the interfaces are 100% fungible. I believe they are, but that needs to be verified. If they are, we should be able to write three controller services: one that implements a generic API for CRUD against Neo4J-style APIs and two that provide connection pooling against the backend to that service. The processor would then defer most of its processing logic to the main controller service like a lot of processor families (ex. HBase and Mongo) do. Graph is a big open question, so for 1.9 we can punt on making the Neo4J capabilities set in stone so you/we can refactor while giving users a chance to play with it--with the understanding that it is an unstable feature set.
