Re: Create a collection of topics
Sure here is how I create multiple topics
Void CreateDynamicTopic(int con)
{
std::string queue_name = std::string("amq.topic/") + "Symbol_Topic_" +
boost::lexical_cast<std::string>(con);
std::string sender_string = queue_name +";{node:{type:topic}}";
connection = qpid::messaging::Connection("127.0.0.1");
connection.open();
connection.setOption("tcp-nodelay", true);
Session session = connection.createSession();
sender = session.createSender(sender_string) ;
sender.setCapacity(sender_capacity);
}
for(int i=0 ; i<900;i++)
{
CreateDynamicQueue(i)
}
I wanted to know if there could be a faster way that I could just pass a
whole list to Qpid and it creates topics from that list

yes, its just creating senders for the amq.topic .
As Gordon Sim said, it's good to create one sender to amq.topic and set the
subject to each message.

It's not actually 'creating' topics, it is just creating senders for the
amq.topic topic, each with a specific default subject.
So you could just create one sender to amq.topic, and then set the
subject of each message you send out.
Not sure if that answers the wider question or not, however(?).
