Hi, our usecase is the following: We have about 800 stores (maybe ~6000 in a few years), all of which want to receive messages for the corresponding store via their own client. This is supposed to happen from the php environment. The topic hierarchy also allows a proper filtering (store ID is included in the topic hierarchy), but we wanted to decide against a filtering on topic level for now, because then we would have to provision a queue for every single store (=> 800 Queues) and would also have to maintain it and ensure that the message quota is not exceeded in case the store fails or goes offline. Thats why we decided to use Selectors in the first place, to avoid the provisioning of so many queues. Do you guys have any other ideas on how we can best implement this usecase?
