Example 1 with TransactionalTopologyBuilder

use of org.apache.storm.transactional.TransactionalTopologyBuilder in project storm by apache.

the class TransactionalGlobalCount method main.

public static void main(String[] args) throws Exception {
    MemoryTransactionalSpout spout = new MemoryTransactionalSpout(DATA, new Fields("word"), PARTITION_TAKE_PER_BATCH);
    TransactionalTopologyBuilder builder = new TransactionalTopologyBuilder("global-count", "spout", spout, 3);
    builder.setBolt("partial-count", new BatchCount(), 5).noneGrouping("spout");
    builder.setBolt("sum", new UpdateGlobalCount()).globalGrouping("partial-count");
    Config config = new Config();
    config.setDebug(true);
    config.setMaxSpoutPending(3);
    try (LocalCluster cluster = new LocalCluster();
        LocalTopology topo = cluster.submitTopology("global-count-topology", config, builder.buildTopology())) {
        Thread.sleep(3000);
    }
}

Example 2 with TransactionalTopologyBuilder

use of org.apache.storm.transactional.TransactionalTopologyBuilder in project storm by apache.
