Example 1 with IdBolt

use of org.apache.storm.perf.bolt.IdBolt in project storm by apache.

the class ConstSpoutIdBoltNullBoltTopo method getTopology.

public static StormTopology getTopology(Map conf) {
    // 1 -  Setup Spout   --------
    ConstSpout spout = new ConstSpout("some data").withOutputFields("str");
    // 2 -  Setup IdBolt & DevNullBolt   --------
    IdBolt bolt1 = new IdBolt();
    DevNullBolt bolt2 = new DevNullBolt();
    // 3 - Setup Topology  --------
    TopologyBuilder builder = new TopologyBuilder();
    builder.setSpout(SPOUT_ID, spout, Helper.getInt(conf, SPOUT_COUNT, 1));
    builder.setBolt(BOLT1_ID, bolt1, Helper.getInt(conf, BOLT1_COUNT, 1)).localOrShuffleGrouping(SPOUT_ID);
    builder.setBolt(BOLT2_ID, bolt2, Helper.getInt(conf, BOLT2_COUNT, 1)).localOrShuffleGrouping(BOLT1_ID);
    return builder.createTopology();
