> Option to use cgroups to limit task resource utilization
> --------------------------------------------------------
>
> Key: AIRFLOW-398
> URL: https://issues.apache.org/jira/browse/AIRFLOW-398
> Project: Apache Airflow
> Issue Type: Improvement
> Components: core
> Reporter: Paul Yang
> Assignee: Paul Yang
> Priority: Minor
>
> Now that tasks have resource requirements specified, Airflow can use the
> defined resource requirements as limits when running the Airflow tasks. A
> common use case is to limit the memory used by a task so that it doesn't
> cause the worker machine to go OOM.
> The proposed idea is to implement a TaskRunner class that, by default,
> executes the Airflow run command in a bash subprocess as it is currently done
> now.
> Alternatively, the user can specify a TaskRunner class that uses cgroups to
> ensure that resource requirements are respected. This would be a lightweight
> approach to limiting resource usage by tasks.
