• startPhase is configured in composition definition element and defines the order of execution of instance elements;
• Any instance element is executed only once;
• All instance elements whit same startPhase are executed at same time in parallel;
• startPhase is used by deploy and unlock; startPhase in reverse order is used by lock, undeploy and delete;

"stage"

To maintain the backward compatibility, we are introducing a new property stepPhasestage.

Minimal support for

...

stage:

• Still valid the startPhase definition for backward compatibility;
• stepPhase stage is configured in composition definition element;
• stepPhase stage  is applied only for migrate operation;
• Any instance element could be executed more then one time; 
• All instance elements whit same stepPhase stage are executed at same time in parallel;

Example of composition definition element stepPhase stage property:

properties:
  stepPhase stage: [0,2]

Default value set to 0.

Full support for

...

stage:

• Still valid the startPhase definition for backward compatibility;
• Using startPhase and stepPhase stage in a composition definition is not valid;
• stepPhase stage is configured in composition definition element;
• Any composition definition element could have different sptePhase for each operation: for example the order for deploy could different for migrate;
• Any instance element could be executed more then one time; 
• All instance elements whit same stepPhase stage are executed at same time in parallel;
• stepPhase stage has not reversal order.

Example of composition definition element stepPhase stage property:

properties:
  stepPhase stage:
    - deploy: [0,1]
    - migrate: [0,2]
    - undeploy: [1]
    - delete: [1]

All not defined operations will be set to 0.
