org.thales.punch.libraries.storm.api.BaseProcessingNode

org.thales.punch.libraries.storm.bolt.TestNode

All Implemented Interfaces:

Serializable, org.apache.storm.task.IBolt, org.apache.storm.topology.IComponent, org.apache.storm.topology.IRichBolt

public class TestNode
extends org.thales.punch.libraries.storm.api.BaseProcessingNode

A simple test vbolt. It allows to fail tuples, once in a while or based on their content. This makes it easy to test the offset and overall behavior of Kafka input connectors.

   "bolt_settings": {
      // to print what is going on
      "verbose" : true,
      
      // fail if the tuple has some filed that contains a string

         or 
         // fail every. Use -1 to disable 
         "fail_every" : 10
      }
