Luke Maycock commented on AIRFLOW-642:
--------------------------------------

We also find this to be an issue. This issue is similar to
https://issues.apache.org/jira/browse/AIRFLOW-70 but the use of a numeric
unique identifier is preferable to a string such as dag_run_id.
Also, it makes sense to address the relationship between xcoms and dag runs
using similar logic.
> Add dag_run to the task_instance table or create new taskuuid column and use
> this to uniquely identify a task

> 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.
