Validator Overview

The Relative Volume validator compares row counts between a target dataset and a reference dataset. You can configure the relative volume validator to monitor the following metrics:

Metric Options	Description
Count Ratio	Calculates the ratio between the number of rows in the target dataset and the number of rows in the reference dataset.
Percentage Ratio	Calculates the the number of rows in the target dataset as a percentage of the number of rows in the reference dataset.

Relative volume validators support reference source configuration for data validation. For more information, see Reference Source Validation. For an overview of all validator types, see Validator Types.
