case class DistinctnessMetric(onColumns: List[String], filter: MetricFilter = MetricFilter.noFilter) extends MetricDescriptor with Filterable with Product with Serializable

A metric that calculates how distinct values in a column are (where a result of 1 is that all values are distinct)

onColumns

- the columns for which distinctness is being calculated over

filter

- the filter to be applied before the distinct count is calculated
