Hello, In the Neutron docs about RPCs and Callbacks system, it is said[1] :
"With the underlying oslo_messaging support for dynamic topics on the receiver we cannot implement a per “resource type + resource id” topic, rabbitmq seems to handle 10000’s of topics without suffering, but creating 100’s of oslo_messaging receivers on different topics seems to crash." I wonder if this statements still holds for the new transports supported in oslo.messaging (e.g Kafka, AMQP1.0) or if it's more a design limitation. I'm interested in any relevant docs/links/reviews on the "topic" :). Moreover, I'm curious to get an idea on how many different resources a Neutron Agent would have to manage and thus how many oslo_messaging receivers would be required (e.g how many security groups a neutron agent has to manage ?) - at least the order of magnitude.
