Re: [openstack-dev] [neutron][lbaas] Can entity calls be made to driver when entities get associated/disassociated with root entity?
Thanks Doug. My apologies for the delayed reply. The change is merged, so replying here. It is a welcome change in one way, there is always a root entity now in perspective while creating any entity. Listener is created with loadbalancer and pool is created with listener. The problem itself is eliminated because there is no DEFERRED stage. But, this restricts pool in one listener. Basically reusing of a pools across listeners and loadbalancers is not possible now. The use case of creating both a HTTPS vip and HTTP vip for the same pool is lost. Basically, a user who will need that, should create 2 pools with the same members and manage them. Is that right? Thanks, Vijay V.

Re: [openstack-dev] [neutron][lbaas] Can entity calls be made to driver when entities get associated/disassociated with root entity?
Hi Vijay, My understanding was that each vendor will have different behavior for entity creation. LBaaS apis will mark each entity as PENDING_CREATE (?) initially and its up to specific vendor driver whether to mark entities as DEFERRED or actually CREATE them on LB. Vendor logic can decide the action based on whether hierarchy/criteria is met per their LB prerequisite.
