Airflow Executor Config
These autoscaler support the following executor config parameters:
executor_config={
"mem_limit": 2048,
"instance_type": "t2.xlarge"
}
- With the help if the
mem_limitparameter, the autoscaler will determin which AWS instance is the right one. instance_typewill overwrite the mem_limit and just crate a instance of that type.
