Author a Time-Based Restriction Policy

  1. Determine your policy scope:
    • Global policy: Click the Policies page icon in the left sidebar and select the Data Policies tab. Click Add Policy and enter a name for your policy.
    • Local policy: Navigate to a specific data source and click the Policies tab. Scroll to the Data Policies section and click Add Policy.

  2. Select Only show data by time from the first dropdown.

  3. Select where data is more recent than or older than from the next dropdown, and then enter the number of minutes, hours, days, or years that you would like to restrict the data source to. Note that unlike many other policies, there is no field to select a column to drive the policy. This type of policy will be driven by the data source's event-time column, which is selected at data source creation.

  4. Choose for everyone, everyone except, or for everyone who to drive the policy. If you choose for everyone except, use the subsequent dropdown to choose the group, purpose, or attribute for your condition. If you choose for everyone who as a condition, complete the Otherwise clause before continuing to the next step.

  5. Opt to complete the Enter Rationale for Policy (Optional) field, and then click Add.

  6. For global policies: Click the dropdown menu beneath Where should this policy be applied, and select On all data sources, On data sources, or When selected by data owners. If you select On data sources, finish the condition in one of the following ways:

    • tagged: Select this option and then search for tags in the subsequent dropdown menu.

    • with columns tagged: Select this option and then search for tags in the subsequent dropdown menu.

    • with column names spelled like: Select this option, and then enter a regex and choose a modifier in the subsequent fields.

    • in server: Select this option and then choose a server from the subsequent dropdown menu to apply the policy to data sources that share this connection string.

    • created between: Select this option and then choose a start date and an end date in the subsequent dropdown menus.

  7. Click Create Policy. If creating a global policy, you then need to click Activate Policy or Stage Policy.
