Examples with RedisStoreBolt org.apache.storm.redis.bolt.RedisStoreBolt used on opensource projects

Example 1 with RedisStoreBolt

use of org.apache.storm.redis.bolt.RedisStoreBolt in project storm by apache.

the class WordCountToBolt method main.

public static void main(String[] args) throws Exception {
    StreamBuilder builder = new StreamBuilder();
    // Redis config parameters for the RedisStoreBolt
    JedisPoolConfig poolConfig = new JedisPoolConfig.Builder().setHost("127.0.0.1").setPort(6379).build();
    // Storm tuple to redis key-value mapper
    RedisStoreMapper storeMapper = new WordCountStoreMapper();
    // The redis bolt (sink)
    IRichBolt redisStoreBolt = new RedisStoreBolt(poolConfig, storeMapper);
    // A stream of words
    builder.newStream(new TestWordSpout(), new ValueMapper<String>(0)).mapToPair(w -> Pair.of(w, 1)).countByKey().to(redisStoreBolt);
    Config config = new Config();
    String topoName = "test";
    if (args.length > 0) {
        topoName = args[0];
    }
    config.setNumWorkers(1);
    StormSubmitter.submitTopologyWithProgressBar(topoName, config, builder.build());
}

Example 2 with RedisStoreBolt

use of org.apache.storm.redis.bolt.RedisStoreBolt in project storm by apache.
