Descrizione

Description

Since execution_date is deprecated, it makes sense that this sensor or a new version of it (for backward compatibility) uses the data_interval variables.

Use case/motivation

I want to make sure that the data interval this DAG is about to operate on is covered by another DAG. For example, data was loaded up to this DAG's data_interval_end.

I believe the sensor itself is simple to write. It just uses data_interval_end rather than execution_date and it doesn't look for one specific task, any external.data_interval_end > self.data_interval_end is acceptable.

This is the equivalent of ExternalTaskSensor with execution_delta set to self.interval_start - closest_external_interval.interval_start which can be calculated manually but will fail later if the external DAG schedule is changed.
