Subject Re: limit policy on bound temporary queues
Date Tue, 18 Dec 2012 08:08:58 GMT
Hi Lance,
let use in address string of the consumers just the exchange name, i.e.:

"amq.fanout"

qpid client will detect from an answer of qpid broker that "amq.fanout" is an existing exchange
and it will create an auxiliary, auto-delete & exclusive queue named like "amq.fanout_18efcccb-3abb-4db4-8ff0-7bb6a8fe0044"
(exchange name, '_' and random UUID) and will bind it to the exchange.

You can also specify routing key (that has no sense for fanout exchange, though) to be used
in the binding, when using address string like "amq.direct/routingKey".


Kind regards,
Pavel Moravec
