Hi all,
Is there a simple way to read the key from a KeyedStream. Very simply I'm trying to read a message from Kafka, separate the incoming messages by a field in the message and write the original message back to Kafka using that field as a new topic. I chose to partition the incoming stream by creating a KeyedStream and using the field from the message as the key. The only thing left is to write the message to Kafka with a producer but i need to know the topic to write to and for that I need to be able to read the key. Is there a way to do this? Is there a better way to do this, rather than using a KeyedStream. Paul
