Description

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.
