Scenario: It has been observed that, in specific situations, a data drift alert is not generated when the count of unique values changes beyond the established percentage threshold.
Threshold set to generate alerts: Change in the unique value count by 5%.
Example: Consider a database containing 100 unique values. If the count of unique values changes by 20%, resulting in a new total of 80 unique records, an alert is not triggered despite the change exceeding the predefined threshold.
Alert: In this case, an alert is not triggered because the number of distinct values exceeds 10. Data Integrity Suite generates alerts for unique value counts only when the number is less than 10. As there are 100 unique values in this scenario, no alert will be generated. For text fields, however, the threshold is higher, and the number of unique values can be up to 100 before an alert is considered.
