Adjustment of the ruleset check scope

By default, a ruleset check is based on a sample of 1,000,000 rows from the dataset. This ensures performance efficiency, especially for very large tables.

However, you can customize the scope of the check — either by increasing or decreasing the sample size or by applying filters to focus the validation on specific parts of the data.

How to adjust the scope

1. Go to the table

2. Click “More” → “Manage ruleset” →"Ruleset check scope"

3. In the scope screen, you can:

• Enter a specific number of rows

• Tick “No row limit” to skip sampling

• Optionally apply a filter to include only specific records

Adjust sample size or filter down to relevant segments.

Use case examples

• Use 100,000 rows to get fast validation during development

• Tick “No row limit” for critical production tables

• Add a filter to validate only rows from the last 30 days

Notes

• Smaller samples reduce computing time but may miss edge cases

• Full dataset checks may increase cost and processing time

• Filters help validate targeted business scenarios
