Subject [jira] [Updated] (SOLR-8888) Add shortestPath Streaming Expression
Date Tue, 29 Mar 2016 13:58:25 GMT

     [ https://issues.apache.org/jira/browse/SOLR-8888?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Joel Bernstein updated SOLR-8888:
---------------------------------
    Description: 
This ticket is to implement a distributed shortest path graph traversal as a Streaming Expression.

possible expression syntax:

{code}
shortestPath(collection, 
                     from="node1", 
                     to="node2",
                     edge="colA,colB",
                     threads="6",
                     partitionSize="300", 
                     fq="limiting query", 
                     maxDepth="10")
{code}
This would start from colA:node1 and traverse from colA to colB iteratively until it finds
colB:node2. The shortestPath function would emit Tuples representing the shortest path.

The optional fq could be used to apply a filter on the traversal.
