Types

type StoredObject

type StoredObject struct {
	// ObjectID uniquely identifies this object in Mongo
	ObjectID primitive.ObjectID `bson:"_id"`

	// UUID uniquely identifies this StoredObject
	UUID string `bson:"uuid"`

	// AppServiceKey identifies the app to which this data belongs.
	AppServiceKey string `bson:"appServiceKey"`

	// Payload is the data to be exported
	Payload []byte `bson:"payload"`

	// RetryCount is how many times this has tried to be exported
	RetryCount int `bson:"retryCount"`

	// PipelinePosition is where to pickup in the pipeline
	PipelinePosition int `bson:"pipelinePosition"`

	// Version is a hash of the functions to know if the pipeline has changed.
	Version string `bson:"version"`

	// CorrelationID is an identifier provided by EdgeX to track this record as it moves
	CorrelationID string `bson:"correlationID"`

	// EventID is used to identify an EdgeX event from the core services and mark it as pushed.
	EventID string `bson:"eventID"`

	// EventChecksum is used to identify CBOR encoded data from the core services and mark it as pushed.
	EventChecksum string `bson:"eventChecksum"`
}
