Public bug reported: It is undesirable to keep many TCP connections open at the same time because doing so consumes system resources and makes it more difficult to scale.
E.g OVS agent creates 15 long-lived connections to rabbitmq from scratch https://paste.opendev.org/show/br2JxQ7SJkX1Ib2Za3jv/ Comparing to Nova which uses 3 connections https://paste.opendev.org/show/bTeFYCTEVX4Hx3YHwJi2/ Agent creates separate topic/RPC server for each resource, like neutron- vo-Network-1.1, neutron-vo-SecurityGroup-1.2, neutron-vo-Port-1.5 and so on. We could combine these calls into couple RPC servers and reduce connection number, oslo.messaging supports connection pool, which could be configured via config, so it manages connections dynamically.
