Field selection
For metricsDuplicates count, Duplicates percentage, Unique count and Unique percentage you have to specify one or several fields. Specifying several fields means field values are concatenated before being counted, which is, for example, useful when validating uniqueness of composite keys.
For metrics Count and Percentage you can pick No field (use record) to count entire records. You can also pick a specific field to count non-NULL values in that field.
For duplicate and unique metrics, Validio includes
NULL values in the counts, unless you apply a NULL filter to remove them.
