Martin Junghanns commented on FLINK-2941:
-----------------------------------------
I assigned it to me for the moment as I am working on the Input and
OutputFormats. The current state can be found here:
[https://github.com/s1ck/flink-neo4j]. Results on first benchmarks are posted
on the [mailing
list|http://apache-flink-mailing-list-archive.1008284.n3.nabble.com/neo4j-Flink-connector-td8792.html]
> Implement a neo4j - Flink/Gelly connector
> -----------------------------------------
>
> Key: FLINK-2941
> URL: https://issues.apache.org/jira/browse/FLINK-2941
> Project: Flink
> Issue Type: New Feature
> Components: Gelly
> Reporter: Vasia Kalavri
> Assignee: Martin Junghanns
> Labels: requires-design-doc
>
> By connecting Flink/Gelly with a graph database like neo4j we can facilitate
> interesting use-cases, like:
> - use neo4j as an input source, i.e. read the complete graph or a subgraph
> from a neo4j database, import it into Flink and run a graph analysis task
> with Gelly.
> - use neo4j as a sink, i.e. perform ETL on some data in Flink to create a
> graph and insert the graph in a neo4j database for further querying.
> We have started a discussion on possible implementations and have looked into
> similar projects, e.g. connecting neo4j to Spark. Some initial thoughts and
> experiences can be found in [this
> document|https://docs.google.com/document/d/13qT_e-y8aTNWQnD43jRBq1074Y1LggPNDsic_Obwc28/edit?usp=sharing].
> Please, feel free to comment and add ideas! I will also start a discussion
> in the mailing list with more concrete problems that we would like to get
> feedback on.
