ai.grakn.factory.TitanHadoopInternalFactory

public class TitanHadoopInternalFactory
extends Object

A Grakn Graph on top of HadoopGraph

This produces a graph on top of HadoopGraph. The base construction process defined by AbstractInternalFactory ensures the graph factories are singletons. With this vendor some exceptions are in places: 1. The Grakn API cannnot work on HadoopGraph this is due to not being able to directly write to a HadoopGraph. 2. This factory primarily exists as a means of producing a GraphComputer on of HadoopGraph
