----------------------------------------
Summary: 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: pools
Reporter: Adrian Bridgett
Priority: Trivial
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.
