func NewPackage(table, operation string) *Package

NewPackage creates a new statistics package for a table and operation.

func (*Package) AddSample ¶

func (p *Package) AddSample(cost float32, rows uint)

AddSample records a cost and row count sample from a query execution.

func (*Package) AddWidthSample ¶

func (p *Package) AddWidthSample(width uint)

AddWidthSample records a result width sample.
