------------------------------------
Summary: [Java Broker] [AMQP 1.0] support Delayed Delivery with
the JMS 2.0 client
Key: QPID-7568
URL: https://issues.apache.org/jira/browse/QPID-7568
Project: Qpid
Issue Type: Improvement
Components: Java Broker
Reporter: Robbie Gemmell
QPID-7255 added a form of delayed delivery support for the Java broker and AMQP
0-X JMS client, with a qpid specific annotation in the case of AMQP 1.0. The
AMQP 1.0 JMS client will also support this via addition of support for JMS 2.0
(QPIDJMS-207), but with some differences than in QPID-7255, and it would be
good for the Java broker to support this too.
The JMS 2.0 client can detect server support for the functionality in two ways:
- by the server offering a "DELAYED_DELIVERY" connection capability
- or, if the connection capability wasn't offered, by setting a desired
capability of "DELAYED_DELIVERY" on the sending link attach and inspecting if
it is offered in the response.
If support for delivery delay was identified, when sending a message with a
producer configured with a delivery delay, the message will carry a
MessageAnnotation with "x-opt-delivery-time" Symbol key and long value
representing the time at which the message can be delivered to receivers as the
number of milliseconds since the epoch. If support was not identified, the send
will fail in order to reflect that the requested delay/delivery-time can't be
satisfied.
