Class AccumuloEntityGraphStore

java.lang.Object

org.calrissian.accumulorecipes.entitystore.impl.AccumuloEntityStore

org.calrissian.accumulorecipes.graphstore.impl.AccumuloEntityGraphStore

All Implemented Interfaces:

EntityStore, GraphStore

public class AccumuloEntityGraphStore
extends AccumuloEntityStore
implements GraphStore

The AccumuloEntityGraphStore wraps an AccumuloEntityStore to provide an extra index which is capable of making edges very fast to traverse for a possibly large set of input vertices. This graph store supports breadth-first traversals.
