Apache Storm bolt possibly timing out

this will help That time (300 seconds) means that once a tuple is emitted by a spout, the topology has 300 seconds to process that tuple and all subsequent tuples that ripple through the topology (through the three bolts) as a result of that tuple.
If the spout emits a second tuple but the first bolt is still processing the first tuple, the clock is still ticking for that second tuple.

hop of those help? Tuple by defintion is an ordered list of objects. tup.values[0] retrieves the object from tuple by position. So it simply returns the first object in the tuple.
Using Apache Camel ProducerTemplate in Apache Storm bolt

hope this fix your issue The root cause of your problem is that you're adding ProducerTemplate to your storm config and it is throwing an exception because it isn't serializable. If that were your own class, you could change the code to make it work but since that is a Camel class I would recommend a different approach.
WebSocketBolt: Change your producerTemplate private member to be transient: private transient ProducerTemplate producerTemplate; so that it will not attempt to be serialized (same problem you have with putting it into conf). WebSocketBolt: Initialize producerTemplate inside your prepare method rather than in your topology.
code :
public class WebSocketBolt extends BaseBasicBolt {
    private transient ProducerTemplate producerTemplate;

    @Override
    public void execute(Tuple input, BasicOutputCollector basicOutputCollector) {
        Status s = (Status) input.getValueByField("tweet");
        producerTemplate.sendBody("direct:main", s.getText());
    }

    @Override
    public void declareOutputFields(OutputFieldsDeclarer outputFieldsDeclarer) {

    }

    @Override
    public void prepare(Map stormConf, TopologyContext context) {
        super.prepare(stormConf, context);
        CamelContext producerTemplate = new RouteStarter().buildRoute();
        this.producerTemplate = producerTemplate.createProducerTemplate();
    }
}

Does that help Tutorial answers your question.
https://storm.apache.org/documentation/Tutorial.html
code :
builder.setBolt("exclaim2", new ExclamationBolt(), 5)
            .shuffleGrouping("words")
            .shuffleGrouping("exclaim1");

Hope that helps Get all object for X minute duration Store them in NoSql database Other bolt triggers zipping and uploading to S3 for every X minute expiry Clear Db for that X minute

it should still fix some issue The problem was solved modifying the filter one code from collector.emit("ack1", new Values(input.getString(0), sig)); to collector.emit( new Values(input.getString(0), sig));
