[AIRFLOW-1467] Allow tasks to use more than one pool slot (#7160)
> allow tasks to use more than one pool slot
> ------------------------------------------

> Key: AIRFLOW-1467
> URL: https://issues.apache.org/jira/browse/AIRFLOW-1467
> Project: Apache Airflow
> Issue Type: Improvement
> Components: scheduler

> It would be useful to have tasks use more than a single pool slot.
> Our use case is actually to limit how many tasks run on a head node (due to
> memory constraints), currently we have to set a pool limit limiting how many
> tasks.
> Ideally we could set the pool size to e.g amount of memory and then set those
> tasks pool_usage (or whatever the option would be called) to the amount of
> memory we think they'll use. This way the pool would let lots of small tasks
> run or just a few large tasks.
