4.5. Ignore Locally Published Messages
You can configure a queue to discard all messages published using the same connection as the session that owns the queue. This suppresses a message loop-back when an application publishes messages to an exchange that it is also subscribed to.
To configure a queue to ignore locally published messages, use the
no-local key in the queue declaration as a key:value pair. The value of the key is ignored; the presence of the key is sufficient.
For example, to create a queue that discards locally published messages using
qpid-config:
qpid-config add queue noloopbackqueue1 --argument no-local=true
Note that multiple distinct sessions can share the same connection. A queue set to ignore locally published messages will ignore all messages from the connection that declared the queue, so all sessions using that connection are local in this context.
