Github user roshannaik commented on the issue: https://github.com/apache/storm/pull/1693 One important thing to include in this API will be to allow users to be explicit about how to handle errors. I don't know if any API out there does it... so this would be unique to Storm. In short: Broadly speaking there are two kinds of tuple process errors that the users need to be concerned about: 1- **Retry worthy Errors** - For instance, failure to deliver to destination service due to connection issues. 2- **Not worth retrying** - For instance, Parsing errors due to bad data in the tuple. These problems can jam up the pipeline if they are retried repeatedly. Such tuples can be sent to a configurable Dead-Letter-Queue.
