[jira] [Created] (SOLR-8888) Add shortestPath Streaming Expression

Joel Bernstein created SOLR-8888:
------------------------------------

             Summary: Add shortestPath Streaming Expression
                 Key: SOLR-8888
                 URL: https://issues.apache.org/jira/browse/SOLR-8888
             Project: Solr
          Issue Type: Improvement
            Reporter: Joel Bernstein


This ticket is to implement a distributed shortest path graph traversal as a Streaming Expression.

possible expression syntax:

shortestPath(colA="node1", colB="node2")

This would start from colA:node1 and traverse from colA to colB iteratively until it finds colB:node2. The shortedPath function would emit Tuples representing the shortest path.
