airflow.providers.standard.operators.datetime¶
Classes¶
| Branches into one of two lists of tasks depending on the current datetime. | 
Functions¶
| 
 | Ensure upper and lower time targets are datetimes by combining them with base_date. | 
Module Contents¶
- class airflow.providers.standard.operators.datetime.BranchDateTimeOperator(*, follow_task_ids_if_true, follow_task_ids_if_false, target_lower, target_upper, use_task_logical_date=False, **kwargs)[source]¶
- Bases: - airflow.providers.standard.operators.branch.BaseBranchOperator- Branches into one of two lists of tasks depending on the current datetime. - For more information on how to use this operator, take a look at the guide: BranchDateTimeOperator. - True branch will be returned when - datetime.datetime.now()falls below- target_upperand above- target_lower.- Parameters:
- follow_task_ids_if_true (str | collections.abc.Iterable[str]) – task_id, task_group_id, or a list of task_ids and/or task_group_ids to follow if - datetime.datetime.now()falls above target_lower and below target_upper.
- follow_task_ids_if_false (str | collections.abc.Iterable[str]) – task_id, task_group_id, or a list of task_ids and/or task_group_ids to follow if - datetime.datetime.now()falls below target_lower or above target_upper.
- target_lower (datetime.datetime | datetime.time | None) – target lower bound. 
- target_upper (datetime.datetime | datetime.time | None) – target upper bound. 
- use_task_logical_date (bool) – If - True, uses task’s logical date to compare with targets. Logical date is useful for backfilling. If- False, uses system’s date.
 
 - choose_branch(context)[source]¶
- Abstract method to choose which branch to run. - Subclasses should implement this, running whatever logic is necessary to choose a branch and returning a task_id or list of task_ids. If None is returned, all downstream tasks will be skipped. - Parameters:
- context (airflow.providers.common.compat.sdk.Context) – Context dictionary as passed to execute()
