-----------------------------------
Summary: IntervalCheckOperator support relative difference ratio and can
ignore zero (was: IntervalCheckOperator support relative difference ratio)
> IntervalCheckOperator support relative difference ratio and can ignore zero
> ----------------------------------------------------------------------------
>
> Key: AIRFLOW-4163
> URL: https://issues.apache.org/jira/browse/AIRFLOW-4163
> Project: Apache Airflow
> Issue Type: Bug
> Reporter: Chao-Han Tsai
> Assignee: Chao-Han Tsai
> Priority: Major
>
> IntervalCheckOperator takes max/min ratio of two values for a metric and
> returns true if it is less than threshold.
> The bug is if one of the values is 0, it assigns the ratio as None. In python
> comparison None < Number is always true. We should change that to fail the
> test
> Also we should support calculating ratio with relative difference.
