> Today, the START commands stored in role_command_orders table are bound to
> multiple stages created based on dependencies between components - a
> component in the second stage can only begin its START after the entire first
> stage is done as opposed to just its dependencies in the first stage. This
> eventually increases the overall blueprint deployment time.
> This Jira tracks STARTing components just based on dependency order as
> specified by the role_command_order as opposed to the current stage based
> model.
> The goal is to be able to configure a direct dependency based execution model
> of commands, for now only for Blueprint based deployment commands.
