This works as intended in other pipelines, which work properly. Tasks in a DAG must only enqueue tasks to. The 'task_partial' is a task object embedded in a partial, so I only need to provide the dag for instantiation. tasks running at a given moment and over 150,000 runs executed per day. For each schedule, (say daily or hourly), the DAG needs to run each individual tasks as their dependencies are met. A dag also has a schedule, a start date and an end date (optional). If the scheduler doesnt appear to be running, or the last heart beat was received several hours ago, your DAGs may not appear in Apache Airflow, and new. I had some issues with the Airflow scheduler and usage of non-UTC timezones in the past, so I wonder, if that could be another reason? from airflow import DAGįrom somewhere import get_localized_yesterday A dag (directed acyclic graph) is a collection of tasks with directional dependencies.

The following DAG was marked for the Monday run as successful, but the task within was never scheduled (thus having no logs whatsoever). I run my Airflow (v1.10.13) pipelines in local time (setup on the VM's timezone).
