Neo4j - Datasource and Datasink

[Fabianexe]

The data model of Neo4j and Gradoop is more or less the same. However, there is no possibility to directly interact with data stored in Neo4j. Many workflows would be benefit if data could be loaded and saved in Neo4j.

I think this is a very good idea. Probably a topic for @p-f or @timo95 ? Or is someone else interested?

There is https://github.com/s1ck/flink-neo4j in case you wanna reuse some ideas.

But we have clearly to differentiate whether it could be Source/Sink or an Importer. The easiest way would be to provide an importer in the first version.

[p-f]

Neo4j provides a JDBC driver, so importing data should work with the RDBMS importer (as soon as that is finished). I don't think that an additional importer would make sense then. We can maybe provide an implementation of our Store API for Neo4j?
