Hi Robert Yes.. I agree that VPN usecase can evolve to SPMC (single-producer-multiple-consumer).. And yes, we should have a way to support SPMC even when we use external datastore.. However I think that support of SPMC can be taken up a next step / phase2..

That depends on what is actually in the deployment: once the routes are ingested they can act as input into multiple use cases. Restricting the data flow to 1:1 really means that we will prescribe how outputs can be consumed -- leading to a deployment where each use case is an integrated silo with little to no flexibility. Now if the deployment calls for both processing BGP routes *and* maintaining VPNs in the underlying network, what is SPSC in the component use cases becomes MPSC...
