Class GSAConfiguration

java.lang.Object

org.apache.flink.graph.IterationConfiguration

org.apache.flink.graph.gsa.GSAConfiguration

public class GSAConfiguration
extends IterationConfiguration

A GSAConfiguration object can be used to set the iteration name and degree of parallelism, to register aggregators and use broadcast sets in the GatherFunction, SumFunction as well as ApplyFunction.

The GSAConfiguration object is passed as an argument to Graph.runGatherSumApplyIteration(org.apache.flink.graph.gsa.GatherFunction, org.apache.flink.graph.gsa.SumFunction, org.apache.flink.graph.gsa.ApplyFunction, int)

addBroadcastSetForGatherFunction

public void addBroadcastSetForGatherFunction(String name,
                                             DataSet<?> data)

Adds a data set as a broadcast set to the gather function.

Parameters:

name - The name under which the broadcast data is available in the gather function.

data - The data set to be broadcast.

addBroadcastSetForSumFunction

public void addBroadcastSetForSumFunction(String name,
                                          DataSet<?> data)

Adds a data set as a broadcast set to the sum function.

Parameters:

name - The name under which the broadcast data is available in the sum function.

data - The data set to be broadcast.

addBroadcastSetForApplyFunction
