Hi Till -- this is in response to your message before about my proposal to add GCS FileSystem/RecoverableWriter support. I was only subscribed to the dev digest before, and so I didn't actually get an email I could reply to, so sorry for the one-off email. I'm properly subscribed to the dev list now.
I've added this PR <https://github.com/apache/flink/pull/14875>related to this effort, and I referenced it from the existing Jira ticket <https://issues.apache.org/jira/browse/FLINK-11838#>. Please let me know what the next steps are. Thanks, Galen
