type Metrics added in v1.70.1

type Metrics struct {
	// RemoteObjects is the count of objects with at least one remote segment.
	RemoteObjects int64

	// InlineObjects is the count of objects with only inline segments.
	InlineObjects int64

	// TotalInlineBytes is the amount of bytes across all inline segments.
	TotalInlineBytes int64

	// TotalRemoteBytes is the amount of bytes across all remote segments.
	TotalRemoteBytes int64

	// TotalInlineSegments is the count of inline segments across all objects.
	TotalInlineSegments int64

	// TotalRemoteSegments is the count of remote segments across all objects.
	TotalRemoteSegments int64

	// TotalSegmentsWithExpiresAt is the count of segments that will expire automatically.
	TotalSegmentsWithExpiresAt int64
}

Metrics represents the metrics that are tracked by this package.

func (*Metrics) Aggregate added in v1.70.1

func (metrics *Metrics) Aggregate(partial Metrics)

Aggregate aggregates the given metrics into the receiver.

func (*Metrics) Reset added in v1.70.1

func (metrics *Metrics) Reset()

Reset resets the invidual metrics back to zero.

type Observer added in v1.70.1

type Observer struct {
	// contains filtered or unexported fields
}

Observer implements the ranged segment loop observer interface for data science metrics collection.

func NewObserver added in v1.70.1

func NewObserver() *Observer

NewObserver instantiates a new rangedloop observer which aggregates object statistics from observed segments.

func (*Observer) Finish added in v1.70.1

func (obs *Observer) Finish(ctx context.Context) error

Finish emits the aggregated metrics.

func (*Observer) Fork added in v1.70.1

func (obs *Observer) Fork(ctx context.Context) (rangedloop.Partial, error)

Fork implements the Observer method of the same name by returning a partial implementation that aggregates metrics about the observed segments/streams. These metrics will be aggregated into the observed totals during Join.

func (*Observer) Join added in v1.70.1

func (obs *Observer) Join(ctx context.Context, partial rangedloop.Partial) error

Join aggregates the partial metrics.

func (*Observer) Start added in v1.70.1

func (obs *Observer) Start(ctx context.Context, startTime time.Time) error

Start implements the Observer method of the same name by resetting the aggregated metrics.

func (*Observer) TestingMetrics added in v1.70.1

func (obs *Observer) TestingMetrics() Metrics

TestingMetrics returns the accumulated metrics. It is intended to be called from tests.
