Class GraknSparkComputer

java.lang.Object

org.apache.tinkerpop.gremlin.hadoop.process.computer.AbstractHadoopGraphComputer

ai.grakn.kb.internal.computer.GraknSparkComputer

All Implemented Interfaces:

org.apache.tinkerpop.gremlin.process.computer.GraphComputer

public final class GraknSparkComputer
extends org.apache.tinkerpop.gremlin.hadoop.process.computer.AbstractHadoopGraphComputer

This is a modified version of Spark Computer. We change its behaviour so it can won't destroy the rdd after every job.
