Class GraknTxTinker

java.lang.Object

ai.grakn.kb.internal.GraknTxAbstract<org.apache.tinkerpop.gremlin.tinkergraph.structure.TinkerGraph>

ai.grakn.kb.internal.GraknTxTinker

All Implemented Interfaces:

GraknTx, GraknAdmin, AutoCloseable

public class GraknTxTinker
extends GraknTxAbstract<org.apache.tinkerpop.gremlin.tinkergraph.structure.TinkerGraph>

A GraknTx using TinkerGraph as a vendor backend.

Wraps up a TinkerGraph as a method of storing the GraknTx object Model. With this vendor some exceptions are in place: 1. Transactions do not exists and all threads work on the same graph at the same time.
