Examples with JoinTLink edu.iu.dsc.tws.tset.links.batch.JoinTLink used on opensource projects

Example 1 with JoinTLink

use of edu.iu.dsc.tws.tset.links.batch.JoinTLink in project twister2 by DSC-SPIDAL.

the class BranchingExample method execute.

@Override
public void execute(WorkerEnvironment workerEnv) {
    BatchEnvironment env = TSetEnvironment.initBatch(workerEnv);
    int para = 2;
    SourceTSet<Integer> src = dummySource(env, COUNT, para).setName("src0");
    KeyedTSet<Integer, Integer> left = src.mapToTuple(i -> new Tuple<>(i % 2, i)).setName("left");
    KeyedTSet<Integer, Integer> right = src.mapToTuple(i -> new Tuple<>(i % 2, i + 1)).setName("right");
    JoinTLink<Integer, Integer, Integer> join = left.join(right, CommunicationContext.JoinType.INNER, Integer::compareTo).setName("join");
    ComputeTSet<String> map = join.map(t -> "(" + t.getKey() + " " + t.getLeftValue() + " " + t.getRightValue() + ")").setName("map***");
    ComputeTSet<String> map1 = map.direct().map(s -> "###" + s).setName("map@@");
    ComputeTSet<String> union = map.union(map1).setName("union");
    union.direct().forEach(s -> LOG.info(s));
}

Example 2 with JoinTLink

use of edu.iu.dsc.tws.tset.links.batch.JoinTLink in project twister2 by DSC-SPIDAL.

the class JoinExample method execute.
