related: #49470, #54813
Why
After Resolve OOM When Reading Large Logs in Webserver #49470 and Add stream method to RemoteIO #54813, we now support memory efficient stream-based read interface (
RemoteIO.streammethod) when reading TaskInstance Logs, but we still need to implement thestreammethod for corresponding RemoteIO on provider side to make the whole reading path memory efficient.What
streammethod onGCSRemoteIOto make TaskInstance Log reading path memory efficientreadmethod to callstreammethod instead of duplicating common logicVerification
I tested the change across the following Airflow versions.
