Threshold-based anomaly alerting #1933
Description
Is your feature request related to a problem? Please describe.
In anomaly detection, it would be helpful to have a configuration available where anomaly alerts are only triggered if the metric value exceeds a specific threshold. For example, I might want to detect anomalies in row counts but only alert if the count is over 20 (to reduce noise from small fluctuations in low-volume tables).
Describe the solution you'd like
Optional config that allows you to set upper / lower thresholds. When set, values will only be flagged as anomalies when they cross those thresholds within the detection period, AND have a significant anomaly_score.
data_tests:
- elementary.column_anomalies:
upper_anomaly_threshold: 20
lower_anomaly_threshold: 5
Describe alternatives you've considered
where_expression applies to the whole model, not just the detection period
