kandi X-RAY | neo4j-scala Summary
The Neo4j Scala wrapper library allows you use Neo4j open source graph database through a domain-specific language. This wrapper is mostly based on the work done by Martin Kleppmann in his Scala implementation of RESTful JSON HTTP resources on top of the Neo4j graph database and Jersey project. See this GIST for a usual Neo4j Matrix Example. You may find Neo4j-Spatial-Scala interesting as well. All discussions (if there are any) see Google Group neo4j-scala.

QUESTION
I'm processing data with Scala 2.11.7 and Flink 1.3.2. Now I'd like to store the resulting org.apache.flink.api.scala.DataSet in a neo4j graph database.
There are Github projects for compatibility:
- Flink with neo4j: https://github.com/s1ck/flink-neo4j
- Scala with neo4j: _https://github.com/FaKod/neo4j-scala
- Flink's graph library "Gelly" with neo4j: _https://github.com/albertodelazzari/gelly-neo4j
What is the most promising way to go? Or should I better use neo4j's REST API directly?
(BTW: Why does stackoverflow restrict the number of links postet...?)
I tried flink-neo4j, but it seems that there are some problems with mixing Java and Scala classes:
