Kevin Watters commented on SOLR-8176:
-------------------------------------
Hey Guys, I know you're really focusing on streaming expressions for graph
traversal, I just wanted to throw it out there. I have a version of it working
based on the GraphQuery. It's completely distributed, the only kicker is, I
implemented it with a dependency on Kafka as a message broker to handle the
shuffling of the frontier query. I was curious if there's a message broker
already in the Solr stack, if so, it should be reasonably easy to swap out the
kafka dependency and then we'll all have a fully distributed graph traversal in
Solr. Let me know what you think,

> Key: SOLR-8176
> URL: https://issues.apache.org/jira/browse/SOLR-8176
> Project: Solr
> Issue Type: New Feature
> Components: clients - java, SolrCloud, SolrJ
> Affects Versions: master
> Reporter: Joel Bernstein
> Labels: Graph
> Fix For: master
>
>
> 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.
