Types

type DB

type DB interface {
	// Store stores storage usage stamps to db replacing conflicting entries
	Store(ctx context.Context, stamps []Stamp) error
	// GetDaily returns daily storage usage stamps for particular satellite
	// for provided time range
	GetDaily(ctx context.Context, satelliteID storj.NodeID, from, to time.Time) ([]Stamp, error)
	// GetDailyTotal returns daily storage usage stamps summed across all known satellites
	// for provided time range
	GetDailyTotal(ctx context.Context, from, to time.Time) ([]Stamp, error)
	// Summary returns aggregated storage usage across all satellites.
	Summary(ctx context.Context, from, to time.Time) (float64, error)
	// SatelliteSummary returns aggregated storage usage for a particular satellite.
	SatelliteSummary(ctx context.Context, satelliteID storj.NodeID, from, to time.Time) (float64, error)
}

DB works with storage usage database.

architecture: Database

type Stamp

type Stamp struct {
	SatelliteID storj.NodeID `json:"-"`
	// AtRestTotal is the disk space used from IntervalStart to IntervalEndTime in Bytes*day
	AtRestTotal float64 `json:"atRestTotal"`
	// IntervalStart represents one tally day
	//  TODO: rename to timestamp to match DB
	IntervalStart time.Time `json:"intervalStart"`
	// IntervalEndTime represents the timestamp for the last tally run time
	//  (i.e. last interval_end_time) for the day
	IntervalEndTime time.Time `json:"-"`
}

Stamp is storage usage stamp for satellite from interval start till next interval.
