> HttpHook is using request module to perform http/https calls. but it is hidden inside implementation. Therefore, it is not possible to choose any value for _pool_connections_ or  _pool_maxsize_ parameters, defaulting to 10. (see [request module documentation|http://docs.python-requests.org/en/latest/api/#lower-lower-level-classes])
> _{{requests.adapters.HTTPAdapter}}_ parameters could probably be passed through Airflow Connection extra parameters ?
> As a consequence, calling a REST API concurrently (using [ThreadPoolExecutor|https://docs.python.org/3/library/concurrent.futures.html#threadpoolexecutor]) is limited to 10 workers maximum. Each additional worker is stopped with the following warning:
> {quote}
> {{\{connectionpool.py\} WARNING - Connection pool is full, discarding connection: my.api.example.org}}

> See [this question on stackoverflow|https://stackoverflow.com/questions/23632794/in-requests-library-how-can-i-avoid-httpconnectionpool-is-full-discarding-con] about Http connexion pools configuration
