Interface PollExceptionStrategy

All Known Implementing Classes:
BridgeErrorStrategy, DiscardErrorStrategy, ReconnectErrorStrategy, RetryErrorStrategy, StopErrorStrategy
public interface PollExceptionStrategy
Strategy to decide when a Kafka exception was thrown during polling, how to handle this. For example by re-connecting and polling the same message again, by stopping the consumer (allows to re-balance and let another consumer try), or to let Camel route the message as an exception which allows Camel error handling to handle the exception, or to discard this message and poll the next message.
