> Handle xcom parameters when running a single task
> -------------------------------------------------
>
> Key: AIRFLOW-154
> URL: https://issues.apache.org/jira/browse/AIRFLOW-154
> Project: Apache Airflow
> Issue Type: Wish
> Components: xcom
> Reporter: Timo
> Priority: Minor
>
> What would be the correct way to handle xcom parameters when running a single
> task in a dag. Simplified example:
> task 1:
> - Push parameter
> task 2:
> - Pull parameter from task 1
> - Push parameter
> task 3:
> - Pull parameter from task 2
> I would like to only run task 2 manually.
> 1. Is it possible to specify any parameters from the commandline that would
> substitute the xcom pull from task 1? [Related issue with
> PR|https://issues.apache.org/jira/browse/AIRFLOW-152]
> 2. What happens with the parameters pushed in task 2? Are they left behind
> somewhere?
