So we _can_ modify an env var, but the issue is that these changes aren't persisted anywhere and will be wiped or reset on a server or container restart, hence its not really a reliable place for long-lived read-write values. So assuming we're doing something like: ``` On every scheduler start-up, check the environment for env vars like `AIRFLOW_POOL_<POOL_NAME>=<size>` For every match, create or update the specified pool to the given size ``` A few uncertainties come to mind: 1) Are we OK with the pool being left there once the env var is removed? 2) Are we OK with the pool being reset to the env-var configured size after being manually updated via the CLI or UI? (since we'd be treating environment variables as the higher-priority source of truth) -- This is an automated message from the Apache Git Service.
