Method Detail

handle

DeserializationExceptionHandler.DeserializationHandlerResponse handle(ProcessorContext context,
                                                                      org.apache.kafka.clients.consumer.ConsumerRecord<byte[],byte[]> record,
                                                                      Exception exception)

Inspect a record and the exception received.

Note, that the passed in ProcessorContext only allows to access metadata like the task ID. However, it cannot be used to emit records via ProcessorContext.forward(Object, Object); calling forward() (and some other methods) would result in a runtime exception.

Parameters:

context - processor context

record - record that failed deserialization

exception - the actual exception
