type Sampler ¶

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

Sampler is a type that reads JSON documents and generates a list of keypaths derived from what it sees.

It works by scanning JSON down to a certain depth, and tracking all keys that it traverses before bottoming out at a scalar value. If it encounters an array, it will traverse all items in the array transparently, however, it will skip arrays of arrays to prevent smashing the stack.

func New(maxDepth int) *Sampler

func (s *Sampler) Keys() []string

func (s *Sampler) KeysAtThreshold(thresholdPercent int) []string

func (s *Sampler) Reset()

func (s *Sampler) Sample(sample []byte) error

func (s *Sampler) Scanned() int

type Stats ¶

type Stats struct {
	DocsScanned     int
	TotalKeys       int
	KeysAtThreshold int
