Copy messages on same broker
Hi,
what is the best way to copy a message from one queue to multiple queues on
the same activemq broker? I have a setup where one queue is filled by an
external process, and a camel based router is used to copy messages to the
destination queues depending on some business logic. I have a recipient
provider function which returns the queue names depending on the exchange.
The activemq IO seems to become the bottleneck since the original message is
being copied twice to two new queues. Is there a low level copy for activemq
where only the indexes are changed, not the message body?
Regards,
Leen

Hi Leen,
Have you tried to disable this option on ActiveMq -->
copyMessageOnSend = false to avoid that activemq copy the message
"You can also further optimise things by setting the copyMessageOnSend
property to be false; which avoids making a copy of the ObjectMessage
to send; though this assumes that you don't try and resuse the
ObjectMessage instance; you just create it once and send it once and
don't try and change the body of the message after sending it."
tcp://localhost:61616?jms.copyMessageOnSend=false

I think this type of questions is an AMQ specific question so please
use the AMQ forum for that.
