Hello,
The new producer org.apache.kafka.clients.producer.KafkaProducer seems to
block on send calls when the cluster is unavailable.
How do I disable this and make send calls fast fail in the event of
unavailable brokers? I know the 0.8.1 Scala-based producer did not block in
that case.
Regards,
/David
The polling errors I get periodically for each unavailable broker:
