--------------------------------------------
Summary: Support AMQP modified disposition frame annotations
Key: ARTEMIS-4997
URL: https://issues.apache.org/jira/browse/ARTEMIS-4997
Project: ActiveMQ Artemis
Issue Type: Improvement
Components: AMQP, Broker
Affects Versions: 2.37.0
Reporter: Jeppe B. Vennekilde
Currently, when ActiveMQ Artemis receives a `Modified` disposition frame, it
ignores the attached annotations if provided.
According to the [AMQP 1.0
spec|https://docs.oasis-open.org/amqp/core/v1.0/os/amqp-core-messaging-v1.0-os.html]
#3.4.5 Modified, if message annotations are provided in the modified
disposition frame, they should be merged with the existing message annotations
and override values where the keys are the same.
We use this feature of AMQP 1.0 to implement a stateless client for the [MADES
Communication
Standard|https://eepublicdownloads.entsoe.eu/clean-documents/EDI/Library/depreciated/503_mades-v1r1.pdf]
which is used extensively by the TSO's (Transmission System Operators) of the
European energy sector.
Modifying the message annotations for a failed message that needs to be retried
later allows us to skip certain processing steps that a message has already
been through that should not be repeated when the message is picked up again.
