# TAR_USAGE_HISTORY

> Total Active Rows (TAR) is the total count of rows made available from Zuora to your Snowflake account in your secure data share.

Total Active Rows (TAR) is the total count of rows made available from Zuora to your Snowflake account in your secure data share.

You can use the `TAR_USAGE_HISTORY` table to monitor the TAR usage of your Snowflake account.

Zuora updates the `TAR_USAGE_HISTORY` table on a daily basis. Each row in this table represents the TAR usage record of a specific Zuora business object.

Zuora does not charge for rows used by the TAR_USAGE_HISTORY table in your secure data share. As such, the TAR_USAGE_HISTORY table does not include row counts from this table itself, whereas soft deleted records of Zuora business objects are included.

## Columns

The following table provides information on columns:

| Column name       | Data type    | Description                                                                             |
