> There is no support to declare dead letter queues with custom arguments. I
> can find a TODO in RabbitMQDeclareSupport class.
> [https://github.com/apache/camel/blob/88f46b1ce46f5cdace73b2721a1cb96a290d42dd/components/camel-rabbitmq/src/main/java/org/apache/camel/component/rabbitmq/RabbitMQDeclareSupport.java#L41]
>
> My requirement is to set a TTL on messages in dead letter queue while queue
> is declared by Camel.
> What I have tried:
> If I create DLQ separately by camel with TTL and use that queue name in
> original queue then I get exception that TTL value can't be different.
> Because the declare parameter in RabbitMQEndpoint class declares both
> original queue and dead letter queue, there is no separate option if someone
> don't want to declare dead letter queue.
> Let me know if there is any workaround except creating queues manually.
