Summary: Add support for Downstream Federated Queues and Addresses
Key: ARTEMIS-2549
URL: https://issues.apache.org/jira/browse/ARTEMIS-2549
Project: ActiveMQ Artemis
Issue Type: New Feature
Components: Broker
Affects Versions: 2.10.1
Reporter: Christopher L. Shannon
Assignee: Christopher L. Shannon
Fix For: 2.11.0
Currently only an upstream can be configured for federation. For flexibility
we should also be able to configure downstream federated brokers. This would
be especially beneficial in scenarios such as a wheel/spoke topology where the
central broker could have all of the upstream/downstream configurations to make
it easy and keep it in the same place.
This feature piggy backs on the existing upstream framework. When a downstream
is configured a message is sent to the other broker on connect and that remote
broker will parse the message and use the information to create an upstream
connection back to the originating broker. If the downstream connection
disconnects or is closed it will terminate the upstream connection. There will
be a flag to share downstream/upstream connections to the same broker.
The downstream configuration can be configured to use HA just like upstreams so
that if it terminates because the remote broker goes down it can failover to
another. The resulting upstream connection that is created back to the
original broker that sent the downstream packet will just be a direct
connection back and doesn't need HA because the downstream manages it on its
side.
See the documentation and examples for more info on how this will work.
