How setup Airflow scheduler to use more than 2 cores?

[nikita-sheremet-java-developer]

I have kubernetes pod with 4 cores where my airflwo scheduler running. But when I look at CPu usage metrics I see that scheduler uses only 2. Is there some settings/restrictions? Any additional configuration apramters to set?

Hi @nikita-sheremet-java-developer, you can tune parsing_processes to increase parallelism when parsing DAGs using https://airflow.apache.org/docs/apache-airflow/stable/configurations-ref.html#parsing-processes. It defaults to 2 processes
