--------------------------------------
Hi [~xintongsong] – sorry for the long delay. I plan to create a new PR and
upload some code this weekend, my other work has let up a bit and I have some
time to look at this. I'll post the link here when it's ready.
> Create RecoverableWriter for GCS
> --------------------------------

> Key: FLINK-11838
> URL: https://issues.apache.org/jira/browse/FLINK-11838

> Issue Type: New Feature
> Components: Connectors / FileSystem
> Affects Versions: 1.8.0
> Reporter: Fokko Driesprong

> Fix For: 1.13.0

> GCS supports the resumable upload which we can use to create a Recoverable
> writer similar to the S3 implementation:
> https://cloud.google.com/storage/docs/json_api/v1/how-tos/resumable-upload
> After using the Hadoop compatible interface:
> https://github.com/apache/flink/pull/7519
> We've noticed that the current implementation relies heavily on the renaming
> of the files on the commit:
> https://github.com/apache/flink/blob/master/flink-filesystems/flink-hadoop-fs/src/main/java/org/apache/flink/runtime/fs/hdfs/HadoopRecoverableFsDataOutputStream.java#L233-L259
> This is suboptimal on an object store such as GCS. Therefore we would like to
> implement a more GCS native RecoverableWriter
