# Row Count

> Verify the number of rows by querying the data and counting records.

## Validator overview

The Row Count validator works similar to the Volume validator configured for the Count metric. By default it counts the entire record. You will need to use filters if you want to specify the exact records to include in the metric calculation.

For more information, see [Volume](https://docs.validio.io/v10.1/docs/validators/validator-types/volume.md) validators. For an overview of all validator types, see [Validator Types](https://docs.validio.io/v10.1/docs/validators/validator-types.md).

## Metric configuration parameters

| Window | Select from a list of windows or create a new window to specify how to aggregate the data. |
| Segmentation | (Optional) Apply segmentation to analyze data in separate groups. Default is `Unsegmented`. |
