[rabbitmq-discuss] Queue Lease (x-expires)

Sun Jan 22 07:40:03 GMT 2012

Thanks Steve and Simon.

I checked that rabbitmqadmin.py uses http calls (RESTful APIs)
provided by RabbitMQ to perform the operations.
Can you provide me a sample
- (either using rabbitmqadmin or using RESTful client) to delete a
queue say "Yogesh" with isEmpty and isUnused flags set to True?
  I could delete the queue using DELETE http request on
http://localhost:55672/api/queues/%2f/Yogesh
  But couldn't figure out a way to specify isEmpty and isUnused flags.
- I was able to do this in a Java client using interface
com.rabbitmq.client.Channel { queueDelete("Yogesh", true, true) }.
  But then, how do I get list of queues using com.rabbitmq.client?

regards, Yogesh
