The autoscale config is commented out since 1.10.10 which is a change from 1.10.9 where it isn't and I think this accounts for the difference in the behavior that people are seeing. https://github.com/apache/airflow/blob/1.10.9/airflow/config_templates/default_airflow.cfg#L480 https://github.com/apache/airflow/blob/1.10.10/airflow/config_templates/default_airflow.cfg#L516 Based on the [comment](https://github.com/apache/airflow/blob/1.10.9/airflow/config_templates/default_airflow.cfg#L477) above the setting, it makes sense that you wouldn't be able to set worker concurrency in 1.10.9: ` If autoscale option is available, worker_concurrency will be ignored` ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
