CountDistinctValuesMetric

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

A metric that calculates the number of distinct values in a column or across several columns

onColumns: - the columns for which you are counting distinct values
filter: - the filter to be applied before the distinct count is calculated
