Subject [jira] [Commented] (STREAMS-344) Support binary protocol in streams-persist-graph
Date Wed, 04 Jan 2017 16:19:58 GMT


ASF GitHub Bot commented on STREAMS-344:

GitHub user steveblackmon opened a pull request:

    STREAMS-344: streams-persist-neo4j

    now that neo4j-java-driver is apache licensed, we can support binding to the binary bolt
endpoint to write and read streams data.
    everything related to neo4j is now in streams-persist-neo4j, leaving only interfaces in
streams-persist-graph for now.
    unlike most other persisters, this module expects to find a valid activity or activityobject
in the datum, not just any document, but then it is able to insert activityobjects as vertices
and activities as edges connecting activityobjects.

You can merge this pull request into a Git repository by running:

    $ git pull STREAMS-344
