Class GraknComputerImpl

java.lang.Object

ai.grakn.kb.internal.computer.GraknComputerImpl

All Implemented Interfaces:

GraknComputer

public class GraknComputerImpl
extends Object
implements GraknComputer

GraphComputer Used For Analytics Algorithms

Wraps a Tinkerpop GraphComputer which enables the execution of pregel programs. These programs are defined either via a MapReduce or a VertexProgram.

A VertexProgram is a computation executed on each vertex in parallel. Vertices communicate with each other through message passing.

MapReduce processed the vertices in a parallel manner by aggregating values emitted by vertices. MapReduce can be executed alone or used to collect the results after executing a VertexProgram.
