As messages arrive on a specific
destination, by default they are sorted in FIFO (first-in, first-out) order,
which sorts ascending based on each message's unique
JMSMessageID
. However, you can use a destination key to
configure a different sorting scheme for a destination, such as LIFO
(last-in, first-out). .
After you configure a destination key, you can select it from within a destination resource, such as a queue, topic, distributed queue, distributed topic, or JMS template if you are using templates to configure your destinations.
