Thanks dims! Good write up,
Other things I noted (more controversial ones); is that we need to come up with a concurrency strategy (and/or guidelines, and/or best practices). At least I feel this will be a way that works and imho implies that one concurrency strategy will (likely) not fit every project; at the best we can do is try to offer best practices.
Also for the pika one, I'd really like to understand why not kombu. I don't know enough of the background, but from that session it looks like we need to do some comparative analysis (and imho get feedback from asksol[1] and others) before we go to deep down that rabbit hole (no jump to another 'greener pasture' imho should be done without all of this, to avoid pissing off the two [kombu, pika] communities).
My 2 cents :-P [1] https://github.com/ask -Josh Davanum Srinivas wrote:
Hi Team, Here are the etherpads from the summit[1]. Some highlights are as follows: Oslo.messaging : Took status of the existing zmq driver, proposed a new driver in parallel to the existing zmq driver. Also looked at possibility of using Pika with RabbitMQ. Folks from pivotal promised to help with our scenarios as well. Oslo.rootwrap : Debated daemon vs a new privileged service. The Nova change to add rootwrap as daemon is on hold pending progress on the privsep proposal/activity. Oslo.versionedobjects : We had a nice presentation from Dan about what o.vo can do and a deepdive into what we could do in next release. Taskflow : Josh and team came up with several new features and how to improve usability We will also have several new libraries in Liberty (oslo.cache, oslo.service, oslo.reports, futurist, automaton etc). We talked about our release processes, functional testing, deprecation strategies and debated a but about how best to move to async models as well. Please see etherpads for detailed information. thanks, dims [1] https://wiki.openstack.org/wiki/Design_Summit/Liberty/Etherpads#Oslo
