Subject [jira] [Updated] (SOLR-8176) Model distributed graph traversals with Streaming Expressions
Date Fri, 25 Mar 2016 22:41:25 GMT


Kevin Watters updated SOLR-8176:
    Attachment: SOLR-8176.patch

Here's a patch with a basic implementation of a Kafka based frontier query broker to support
distributed graph query traversal in Solr.  The unit test is commented out because it requires
a Kafka broker to be running.  Also, there's some config parameters / properties that are
hard coded.  Either way, this shows how to use the GraphQuery in a distributed graph traversal

> I think it would be useful to model a few *distributed graph traversal* use cases with
Solr's *Streaming Expression* language. This ticket will explore different approaches with
a goal of implementing two or three common graph traversal use cases.
