Each media type is handled by a Service - Media (handlers) service.

The Media Manager service handles shared orchestration of the Media Handler services.

Repository

DynamoDB tables

Standard Config Table Per Service

Configuration tags

{
	configKey: "MediaGraphServiceName"
	configTag: "MediaGraphServiceName"
	configValue: xxx // eg: "MediaGraph"
}

{
	configKey: "MediaHandlerService"
	configTag: xxx // mediaHandlerServiceNameTag, eg: "MediaStandard", this is what is saved in each media node
	configValue: {
		serviceName: xxx // eg: "ImageStandard", this is the actual deployed service name}
	}
}

Media

Records which Handler manages each media element 

{
	mediaId
	mediaHandlerServiceNameTag
}
  • partition key: mediaId
  • sort key: (none)

Graph database

Service - Media Graph

Nodes

{
	nodeLabel: "mediaPropertyLabel",
}
{
	nodeLabel: "mediaProperty",
}

Relationships

}
{
	relationshipType: "disabled_mediaProperty",
}
{
	relationshipType: "is_mediaPropertyLabel",
}
