@kapa.ai. Looking to set something up to get alerts if some source tables do not get updated. I am testing Elementary Cloud. I have three options in mind: dbt source freshness, elementary freshness_anomalies tests and the automated out of the box freshness tests in Elementary Cloud. The last option, the out of the box one, is not working reliably so far. Can you explain the differences between the three approaches and when to use each one? Is there a better option?
