Types

type QueryService

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

QueryService contains span utils required by the query-service.

func NewQueryService

func NewQueryService(spanReader spanstore.Reader, dependencyReader dependencystore.Reader, options QueryServiceOptions) *QueryService

NewQueryService returns a new QueryService.

func (QueryService) Adjust

func (qs QueryService) Adjust(trace *model.Trace) (*model.Trace, error)

Adjust applies adjusters to the trace.

func (QueryService) ArchiveTrace

func (qs QueryService) ArchiveTrace(ctx context.Context, traceID model.TraceID) error

ArchiveTrace is the queryService utility to archive traces.
