Cloned from launchpad blueprint https://blueprints.launchpad.net/heat/+spec/stack-convergence.

Description:

It may be useful for Heat to have a mechanism for self-healing and/or convergence. i.e., if an underlying resource disappears or goes into an error state for whatever reason, it would be nice for Heat to have a mechanism to fix or delete/recreate the underlying resource, either explicitly through user action ("heat converge") or implicitly (based on a schedule?).
