> 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.
