Description RHOS Integration 2014-01-07 05:03:21 UTC 
Cloned from launchpad blueprint https://blueprints.launchpad.net/heat/+spec/improve-api-polling.

Description:

Heat polls a resource's API (eg. Nova, Trove) every second during resource creation to check the status of the resource.  Several concurrent stack-creates can cause a high number of requests to the API and trigger the API's rate-limiting, which results in a stack-creation failure.

Polling should either be spaced more appropriately (polling intervals get longer as time passes) or eliminated in favor of using a notification system, if possible.
