Re: [Openstack] Versioning for notification messages

Hi All, I guess I may have mis-stated the problem a tad in talking about version numbering. The notification system is an outbound interface, and my interest is in being able to write consumers with some guarantee that they won't be broken as the notification message format evolves. Having

Re: [Openstack] Versioning for notification messages

If we want to have a notification system that could handle messages with different payloads and different versions, we have two options: 1) detect the version of the payload in the notification message 2) add a version number in the notification message Option 1 sounds to me like something hard t

Hi, Great job ! I suggest some things : - glance add command is deprecated, please use "glance image-create". - no need to modify ownership for nova. - typo here : /etc/cinder/api-paste.init (it's a INI file) - for Quantum, you are using the use case in which only one tenant can reach external

Re: [Openstack] Versioning for notification messages

Whilst a version number would allow a consumer to detect that something has changed, it doesn't really help in providing any kind of backward compatibility. Consider the following scenario: There are a bunch of systems external to Nova developed to consume notification messages, and someone intr

Re: [Openstack] Versioning for notification messages

If you are proposing a new interface to the existing notification system that could be stable enough to 'survive' multiple versions, then I agree. The trade-off is we will loose information of the payload, unless somebody out there have a magic solution for this (and probably the version number is

Hey Howard, Queues are generally in memory, but you may turn on persistent (disk) queues in your environment. So that's your limitation. Having rabbitmq on a different server is a good idea. Also, Queues are only used for control, not user data, so they shouldn't be that big of a burden. Havi
