Hi @tejaschowsalkar ,
Can you elaborate on your use case a bit more?
A queue is ultimately something that is owned by an application that can then apply subscriptions to it (or have them applied by an admin) in order to attract messages to it. In other words it should be well know to the application owning the queue. Why are you trying to find a queue (or queues?) based on a subscription?
Are you looking to figure out how many apps have subscribed to a specific topic?
Keep in mind that Solace supports wildcards, so there may be many many different permutation of subscriptions that could attract a specific topic.
