The consumer will reconnect and the message duplication is not expected. We produce 505 messages. The PerformanceConsumer will ack the messages (0-500) with the transactions and then commit the transactions. When the consumer reconnects, we hope only the messages (501-505) can be received. Because the transaction commit is [async](https://github.com/apache/pulsar/blob/master/pulsar-testclient/src/main/java/org/apache/pulsar/testclient/PerformanceConsumer.java#L359), the last transaction may not have been committed. And then the consumer will receive message (400 - 505). -- This is an automated message from the Apache Git Service.
