About Filters

Use filters to specify the datapoints or records you want to include in a validator metric calculation or segmentation fields. For a detailed reference of each filter type, see Filter Types. The following table lists the types of filters that Validio supports:

Filter Types	Description
No Filter	No filter applied to data. Process all available datapoints in a Window.
Boolean Filter	Ensures that a Boolean value is either true or false.
Enum Filter	Ensures that a string only contains values from a fixed set of specified values.
Null Filter	Ensures that a field value is NULL.
String Filter	Ensures that a string adheres to certain criteria.
SQL Filter	Filter records based on a SQL WHERE statement.
Threshold filter	Ensures that a numeric value is either under or over a certain threshold.

When to configure filters

You can configure filters on both validators and segmentations:

Configure filters on validators to specify the datapoints to include in the metric calculation. For example, to count only the NULL values for a certain field, use a volume validator and apply a NULL filter.
Configure filters on segments to specify the values to include in the segmentation. Because segments will be created before the validator metric, it’s better to apply filters related to the segments on the segmentation. Then, you can configure validators to use the filtered segmentation.
