Every time lost couple of messages when the target broker is shutdown

[codevally]

Hi Experts

I am working on a test with Spring-AMQP and Rabbit server 2.8.2 version.

The test is basically related to the fail-over and every time the test lost some messages (4-5) when I shutdown the target rabbit server. Is there any way to overcome this?

How do I test
1. Sending batch of messages with spring-amqp.
2. While the program send messages, I am killing the target rabbit server.
3. Spring-amqp connects to the other cluster node. But within that connection transition, some messages are lost.

Thanks,

/Roshan.

Transactions and HA queues.

However, you'll get much better performance with publisher confirms (but it requires your client to keep track of unconfirmed messages and resend them).
