Hi all, we are running a bridge between our old middleware and qpid system which at startup queries the existing middleware for the number of broadcast groups it knows about. It is a pricing system so there are ~20000.
The bridge creates a fanout exchange for each broadcast group, creates a queue and binds it to the exchange. All this takes ~75 seconds for 20000. Not a problem. When we add a SubscriptionManager.subscribe() to the loop we get though 1000 requests in ~3 minutes. I have created an example below which exhibits the problem. The question are we using the SubscriptionManager incorrectly? Is there a better way for us to achieve the result we require? for (int i=0; i < 20000; ++i) { std::stringstream ss; ss << "listener" << i; // Try and declare the exchange. Will succeed even if it already exists. oSession.exchangeDeclare(qpid::client::arg::exchange=ss.str(), qpid::client::arg::type="fanout", qpid::client::arg::alternateExchange=std::string(), qpid::client::arg::passive=false, qpid::client::arg::durable=true); oSession.queueDeclare(qpid::client::arg::queue=ss.str(), qpid::client::arg::exclusive=true, qpid::client::arg::autoDelete=false); oSession.exchangeBind(qpid::client::arg::exchange=ss.str(), qpid::client::arg::queue=ss.str(), qpid::client::arg::bindingKey=ss.str()); oSubscriptionManager.subscribe(*this, ss.str()); } Regards, Dave The information contained in this email is strictly confidential and for the use of the addressee only, unless otherwise indicated.
