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.
