type InjuredSegment

type InjuredSegment struct {
	StreamID uuid.UUID
	Position metabase.SegmentPosition

	SegmentHealth float64
	AttemptedAt   *time.Time
	UpdatedAt     time.Time
	InsertedAt    time.Time
}

InjuredSegment contains information about segment which should be repaired.

type RepairQueue

type RepairQueue interface {
	// Insert adds an injured segment.
	Insert(ctx context.Context, s *InjuredSegment) (alreadyInserted bool, err error)
	// Select gets an injured segment.
	Select(ctx context.Context) (*InjuredSegment, error)
	// Delete removes an injured segment.
	Delete(ctx context.Context, s *InjuredSegment) error
	// Clean removes all segments last updated before a certain time
	Clean(ctx context.Context, before time.Time) (deleted int64, err error)
	// SelectN lists limit amount of injured segments.
	SelectN(ctx context.Context, limit int) ([]InjuredSegment, error)
	// Count counts the number of segments in the repair queue.
	Count(ctx context.Context) (count int, err error)

	// TestingSetAttemptedTime sets attempted time for a segment.
	TestingSetAttemptedTime(ctx context.Context, streamID uuid.UUID, position metabase.SegmentPosition, t time.Time) (rowsAffected int64, err error)
}
