[ovirt-users] Questions about VDSM communication protocol

Hello, 1. I know vdsm communication adopted rpc over "stomp" and i'm wondering if it's due to use of the message broker or any other purpose. 2. according to https://www.ovirt.org/develop/release-management/features/infra/jsonrpc.html, vdsm has the final plan to completely separate msg broker. Is it still valid and under development? 3. if so, why is vdsm trying to use msg broker? because it seems enough even without msg broker. thanks,
