Fields Grouping

2021SC@SDUSC
以代码为例：
public class Toplogy {

public static void main(String[] args) {

TopologyBuilder builder = new TopologyBuilder();
builder.setSpout("spout", new Spot(), 1);
builder.setBolt("bolt",new Bolt() , 3).fieldsGrouping("spout", new Fields("field0"));

Config conf = new Config();
conf.setDebug(false);

LocalCluster cluster = new LocalCluster();
cluster.submitTopology("toplogy", conf, bu

Fields Grouping最先出现在Python成神之路。
