Subject [jira] [Commented] (FLINK-2941) Implement a neo4j - Flink/Gelly connector
Date Sat, 27 Feb 2016 15:44:18 GMT

    [ https://issues.apache.org/jira/browse/FLINK-2941?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15170625#comment-15170625

Martin Junghanns commented on FLINK-2941:
-----------------------------------------

I finished the input and output formats https://github.com/s1ck/flink-neo4j

My tests have a dependency to Neo4j, which is GPL licensed. The main sources have no dependency
to Neo4j. Please let me know how to proceed (e.g. integration in flink-batch-connectors).

> 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.
