Types

type DB

type DB interface {
	// GetSatellite retrieves that satellite by ID
	GetSatellite(ctx context.Context, satelliteID storj.NodeID) (satellite Satellite, err error)
	// InitiateGracefulExit updates the database to reflect the beginning of a graceful exit

	// UpdateGracefulExit increments the total bytes deleted during a graceful exit
	UpdateGracefulExit(ctx context.Context, satelliteID storj.NodeID, bytesDeleted int64) error
	// CompleteGracefulExit updates the database when a graceful exit is completed or failed
	CompleteGracefulExit(ctx context.Context, satelliteID storj.NodeID, finishedAt time.Time, exitStatus Status, completionReceipt []byte) error

DB works with satellite database

architecture: Database

type ExitProgress

type ExitProgress struct {
	SatelliteID       storj.NodeID
	InitiatedAt       *time.Time
	FinishedAt        *time.Time
	StartingDiskUsage int64
	BytesDeleted      int64
	CompletionReceipt []byte
	Status            int32
}

ExitProgress contains the status of a graceful exit

type Satellite

type Satellite struct {
	SatelliteID storj.NodeID
	AddedAt     time.Time
	Status      int32
}

Satellite contains the satellite and status

type Status

type Status = int

Status refers to the state of the relationship with a satellites
