Monitor number of records, non-NULL values, duplicates, unique values etc.


Optionally, create a Destination to write out datapoints to a Destination, before you configure a Volume Validator.

Configuration details


The Destination parameter allows writing out data to a specified Destination for follow-up inspection. This means that data caught by the filter in this Validator can be stored in a separate table or bucket.

Field selection

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.

**Volume** Validator Configuration Wizard - Single field in Source config.

Volume Validator Configuration Wizard - Single field in Source config.

For metrics Duplicates 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.

Note: For duplicate- and unique metrics, Validio counts NULL values as any other value, unless you apply a NULL filter.

**Volume** Validator Configuration Wizard - Multiple fields in Source config.

Higher sensitivity means that the accepted range of values is narrower, which identifies more anomalies. Conversely, lower sensitivity values imply a wider range of accepted values, which identifies fewer anomalies.
