Brad Harvey commented on ARTEMIS-3693:
--------------------------------------
Others may also like to disable duplicate detection entirely at the address
level.

> {quote}As an artemis user
> I want the broker to ignore duplicate messages but still process unique
> messages that are received in the same transaction and successfully commit
> Instead of failing to commit the whole transaction and rejecting both the
> duplicates and unique messages
> So that I don't have to implement custom error handling to sort out the
> duplicates from uniques and retry the uniques

> The current duplicate detection returns an error back to producers, which
> forces the producer to implement custom error handling to distinguish this
> error from others.

> This is particularly problematic when multiple messages are sent in the same
> transaction - some may be duplicates while others are not, but they will all
> be rejected. Difficult for the sender to untangle which is which.

>
> *Proposed Solution*
> Add configuration at the address level to silently drop duplicates instead of
> rejecting them.
> Update documentation to describe the new option.
