Convergence Design

This page proposes the design for the convergence blueprints.
Note: Currently this page does not address design for 3rd blueprint "Convergence continuous observer"

Flow Diagrams

Flowchart

Sequence

Data Model Change

Data model for persisting the graph

Add a new table 'resource_graph'

Column name	Type	Constraint
resource_id	varchar(36)	NOT NULL ForeignKey resource.id
needed_by	varchar(36)	NULL ForeignKey resource.id
stack_id	varchar(36)	NOT NULL ForeignKey stack.id
retry_count	Integer	Default (0)
observed_ready	Boolean	Default False

Stack Create Flow

Numbered list item

Heat engine parses the template and upon successful validation it persists the template, stack ,all the resources and the graph. [Currently only stack and template are stored as part of stack.store() ]
