----------------------------------
Summary: Add dag_run to the task_instance table or add taskUUID
and use this to uniquely identify a task
Key: AIRFLOW-642
URL: https://issues.apache.org/jira/browse/AIRFLOW-642
Project: Apache Airflow
Issue Type: Improvement
Components: DagRun, scheduler
Reporter: Arunprasad
We are planning to run around 40,000 tasks a day using airflow and some of them
are critical to give quick feedback to developers.
Currently having execution date to uniquely identify tasks does not work for us
since we mainly trigger dags (instead of running them on schedule) we collide
with 1 sec granularity on several occasions. Having a task uuid or associating
dag_run to task_instance table and using this for scheduling and updating
status will help us here.
