Hi Naveen, I'm not an expert in ActiveMQ Artemis, and may answer incorrectly, but I have seen some cases when temporary queues are used. Usually there is no need to use management API to create a temporary queue. As it seems to me, the purpose of temporary queues is to be auto-created and auto-deleted without any management actions.
Temporary queue is created under some address, and the address can also be temporary (if the application has permissions to delete it when disconnecting). For example, when running JMSToolBox (open source utility for working with different message brokers), it connects to Artemis and creates (or requests to auto-create?) an address with an UUID-like name with the same queue. Another case of using temporary queues is non-durable subscription. When an application subscribes to the topic (multicast address), in some conditions it creates a temporary queue on this address. There should be createNonDurableQueue, deleteNonDurableQueue permissions on this address, and createAddress if an address also doesn't exist. As far as I know, address-settings should also allow auto-creation of addresses and queues. Permissions can be granted to the address and fully-qualified queue name, but temporary queue names are usually random. If an application uses a temporary queue on the specific address, it is possible to grant permissions to this address (and all queues on this address). It is not possible to specify granular permissions for the address when it's name is random, but one of our developers has made some small change in JMSToolBox Artemis module which adds some prefix to the name, so we can add permissions on this prefix and grant any user to connect with JMSToolBox without having full permissions on the broker. We have used two methods to configure permissions: API operation addSecuritySettings, and security-settings in the broker.xml (the latter was preferable for us). ср, 24 апр. 2024 г. в 19:30, Naveen kumar <gnaveen.g...@gmail.com>: > Hi Team, > > Any update please ? > > Regards , > Naveen > > > On 22 Apr 2024, at 5:25 PM, Naveen kumar <gnaveen.g...@gmail.com> wrote: > > > > Hi Team, > > > > Any update on below please ? > > > > Regards, > > Naveen > > > >> On 16 Apr 2024, at 11:59 AM, Naveen kumar <gnaveen.g...@gmail.com> > wrote: > >> > >> Hi Team, > >> > >> We have the below question on temporary queues in Artemis MQ in eks . > Could you please help us with answer for the below ones, > >> > >> 1.
