Class GraknTxJanus

java.lang.Object

ai.grakn.kb.internal.EmbeddedGraknTx<org.janusgraph.core.JanusGraph>

ai.grakn.kb.internal.GraknTxJanus

All Implemented Interfaces:

ai.grakn.GraknTx, ai.grakn.kb.admin.GraknAdmin, AutoCloseable

public class GraknTxJanus
extends EmbeddedGraknTx<org.janusgraph.core.JanusGraph>

A GraknTx using JanusGraph as a vendor backend.

Wraps up a JanusGraph as a method of storing the GraknTx object Model. With this vendor some issues to be aware of: 1. Whenever a transaction is closed if none remain open then the connection to the graph is closed permanently. 2. Clearing the graph explicitly closes the connection as well.
