Helloo, We've tried to use AliCloud OSS (like S3 in Amazon) as Pinot deep storage. There is no pinot-oss deep storage plugin right now but we are able to use OSS as pinot deep storage using the pinot hdfs file system plugin. We created a documentation for that; https://docs.pinot.apache.org/users/tutorials/use-oss-as-deep-storage-for-pinot

Thanks a lot for this contribution
