Why does getting the instance id require the API to block? I can create 1 or 1000 UUIDs in order (1) time in the API server and hand back 1000 instance ids in a list of <server> entries in the same amount of time. I'm more concerned about an external user hitting the API server 1000 times to generate a 1000 instance request, then hitting the API server 1000 more times to check the status until a 1000 instances return "running". That's a lot of socket connections.
The SeverDetailsResponse isn't a list? You can't just return: <server> ... </server> <server> ... </server> <server> ... </server> Brian Schott, CTO Nimbis Services, Inc. brian.sch...@nimbisservices.com On May 23, 2011, at 11:52 AM, Ed Leafe wrote: > On May 23, 2011, at 11:41 AM, Jorge Williams wrote: > >> I don't see how that peculates anything.
