I'm guessing as to how this is implemented, but if a producer sends a message to the virtual topic, is it copied to 20 separate queues? If the messages are copied to different queues, is this done in some sort of transaction on the broker? Say only 9 of the 20 queues get the copied message before a broker failure, does this transaction fail, and are all copies rolled back? Any help appreciated. -- View this message in context: http://www.nabble.com/Virtual-Topics-Destinations-and-error-handling-tf3568566s2354.html#a9969261 Sent from the ActiveMQ - User mailing list archive at Nabble.com.
