Discussion onTransaction Ordering. In this design, we are assuming that the consumer delivers messagesin offset orderto preserve the behavior that Kafka users currently expect. A different way is todeliver messages in “transaction order”: as the consumer fetches commit markers, it enables the corr...

This is the maximum time librdkafka may use to deliver a message (including retries). Delivery error occurs when either the retry count or the message timeout are exceeded. The message timeout is automatically adjusted to transaction.timeout.ms if transactional.id is configured. Type: integer ...
