Example 1 with RedisClusterStateUpdater

use of org.apache.storm.redis.trident.state.RedisClusterStateUpdater in project storm by apache.

the class WordCountTridentRedisCluster method buildTopology.

public static StormTopology buildTopology(String redisHostPort) {
    Fields fields = new Fields("word", "count");
    FixedBatchSpout spout = new FixedBatchSpout(fields, 4, new Values("storm", 1), new Values("trident", 1), new Values("needs", 1), new Values("javadoc", 1));
    spout.setCycle(true);
    Set<InetSocketAddress> nodes = new HashSet<InetSocketAddress>();
    for (String hostPort : redisHostPort.split(",")) {
        String[] hostPortSplit = hostPort.split(":");
        nodes.add(new InetSocketAddress(hostPortSplit[0], Integer.valueOf(hostPortSplit[1])));
    }
    JedisClusterConfig clusterConfig = new JedisClusterConfig.Builder().setNodes(nodes).build();
    RedisStoreMapper storeMapper = new WordCountStoreMapper();
    RedisLookupMapper lookupMapper = new WordCountLookupMapper();
    RedisClusterState.Factory factory = new RedisClusterState.Factory(clusterConfig);
    TridentTopology topology = new TridentTopology();
    Stream stream = topology.newStream("spout1", spout);
    stream.partitionPersist(factory, fields, new RedisClusterStateUpdater(storeMapper).withExpire(86400000), new Fields());
    TridentState state = topology.newStaticState(factory);
    stream = stream.stateQuery(state, new Fields("word"), new RedisClusterStateQuerier(lookupMapper), new Fields("columnName", "columnValue"));
    stream.each(new Fields("word", "columnValue"), new PrintFunction(), new Fields());
    return topology.build();
