------------------------------------
Summary: Add ability for Kafka Spout to do limited retries on
failed tuples, and redirect down a "failed" stream
Key: STORM-1869
URL: https://issues.apache.org/jira/browse/STORM-1869
Project: Apache Storm
Issue Type: Improvement
Components: storm-kafka
Reporter: Stephen Powis
h4. Summary
KafkaSpout provides no way to limit the number of times a tuple can fail within
your topology. I think it'd be great to allow configuring a hard limit to the
number of times a tuple can be failed before it is no longer retried.
Additionally, it'd be fantastic if the spout could do a one-time emit of this
tuple down a "failed" stream. This stream would allow you to handle these
failed tuples in some way -- persist the failed tuple to some other storage
system to be replayed later? logged? ignored? tons of things you could
possibly want to do with these.
