Can I achieve this with BaseOperator? I doubt We use it for backfill as well when Airflow starts our query and provides time intervals ########## airflow/providers/yandex/operators/yandexcloud_yq.py: ########## @@ -0,0 +1,89 @@ +# Licensed to the Apache Software Foundation (ASF) under one +# or more contributor license agreements.

Any situations when caching is preferable? More ver it would be nice to call "hook.close()" when it is not needed anymore. Current code is quite straightforward: creates hook in execute and destroys it in on_kill. -- This is an automated message from the Apache Git Service.
