Preserving Concurrency while using spring acknowledgement

[tec]

Hi all,
Is there any way that we can preserve the order of messages in the queue while using a exponential backoff policy.We are running multiple instance of queue consumers.

Thanks,

Once you have more than one consumer, there is no way to preserve ordering; the exponential backoff simply widens the timing window and makes the reordering more likely.
