Motivation
This test sometimes blocks at
consumer.receive()at line 261. The problem is introduced in this PR #23986. For batch sending scenarios, the current way of creating producers cannot guarantee that all messages are sent out in one batch. Therefore, for batch messages, executingconsumer。negativeAcknowledgeonly once is not enough.Modifications
By adding
batchingMaxPublishDelaywhen creating the producer, all messages are guaranteed to be sent together.Documentation
