Apache Storm: get Topology name inside a Bolt
Question
How can I get the name of the current topology inside a BaseRichBolt implementation? I see that I have access to the stormConfig Map and the TopologyContext from the prepare() call, but it isn't obvious how to get the name of the running topology from either of these.

You can get it from the config map.
Use config.get(Config.TOPOLOGY_NAME)
