Default queues durable or not
Hi,
By default queues and exchanges are durable or not? my java client creates
queues and they are showing durable: true so just wanted to know what is
the default behavior.
Thanks,
Ram

As per my previous mail, can you show how you are currently creating
the queue (an address string?), and I can see how it can be modified
to create with the desired durability.
Thanks,
Rob

From the client side is there any argument that I can pass to create with
ALWAYS for Java client?

Unfortunately the default of DEFAULT is currently hardcoded - I'll
raise a JIRA to change that so it takes the default from a context
variable which you can override with system properties / initial
config.
How are your clients currently creating the queues - however they are
doing it we should be able to alter the command in some way to create
the queue with the desired default?

Re: Default queues durable or not

Rob,
I know its a old post but i ran into this issue again, i have clients
create queues dynamically based on some condition so the ques are getting
that flag messageDurability to DEFAULT, how can i make it to create as
ALWAYS? is there a way to set this value globally or is there a way to
specify queue initial config where i can specify default configs that can
apply to all the queues created by client? In other words can i have broker
configration to set messageDurability to ALWAYS using broker configuration?
Thanks,
Ram

Re: Default queues durable or not
Posted by Rob Godfrey <ro...@gmail.com>.
A "durable" object in the Java Broker is one which has its configuration
persisted to a durable configuration store. When created through the REST
API, objects where the durability is not explicitly provided will default
to durable=true. Note that a queue being durable is a necessary but not
sufficient condition for messages enqueued on that queue to survive broker
restart - for message enqueues to survive restart the messages must be sent
as persistent, or the queue must be configured to have the
"messageDurability" set to "ALWAYS".
Hope this helps,
Rob

Thank you, but when i did exchange api call i see default exchanges are
durable.
curl -s 0:10001/rest/exchange
[ {
"name" : "amq.direct",
"id" : "eebe6f3e-0f3e-3788-8d2c-7b933483b1df",
"state" : "ACTIVE",
"type" : "direct",
"durable" : true,
"createdTime" : 0,
"lifetimePolicy" : "PERMANENT",
"statistics" : {
"bytesIn" : 0,
"bindingCount" : 0,
"messagesDropped" : 0,
"bytesDropped" : 0,
"messagesIn" : 0
}
},
What does it mean?

RE: Default queues durable or not

You're confusing two concepts... store-and-forward is something any AMQP broker will do. Persisting a message across broker restarts is a feature that needs to be enabled by both the broker and the client. "Durable" is the latter.
Qpid brokers don't do durable messages by default but it is certainly easy to turn it on - the default is not a reason to switch brokers, and the client sending the message needs to specify its durability anyway.

By Default Qpid Routers and Brokers are not durable, it will send the message as if Consumer is listening and it ensures the successful delivery of the message to the consumer hoping that consumer is up and running always. In case if your environment didn't have all the consumers up and running then use any of the store and forward brokers like activemq.
Hope this helps if not let me know.

Hi,
By default queues and exchanges are durable or not? my java client creates queues and they are showing durable: true so just wanted to know what is the default behavior.
