示例1: buildDevicesTopology

import org.apache.storm.starter.spout.RandomNumberGeneratorSpout; //導入依賴的package包/類
/**
 * Creates a topology with device-id and count (which are whole numbers) as tuple fields in a stream and it finally
 * generates result stream based on min amd max with device-id and count values.
 */
public static StormTopology buildDevicesTopology() {
    String deviceID = "device-id";
    String count = "count";
    Fields allFields = new Fields(deviceID, count);

    RandomNumberGeneratorSpout spout = new RandomNumberGeneratorSpout(allFields, 10, 1000);

    TridentTopology topology = new TridentTopology();
    Stream devicesStream = topology.newStream("devicegen-spout", spout).
            each(allFields, new Debug("##### devices"));

    devicesStream.minBy(deviceID).
            each(allFields, new Debug("#### device with min id"));
