tl;dr - Use case is reading metadata such as ACLs, owner, etc. about GCS objects
Hi, I am attempting to write a Dataflow job that reads a bunch of GCS objects and inspects their metadata (especially the ACLs). I have attempted to get information from MatchResult.Metadata <https://beam.apache.org/documentation/sdks/javadoc/2.6.0/org/apache/beam/sdk/io/fs/MatchResult.Metadata.html> and ResourceId <https://beam.apache.org/documentation/sdks/javadoc/2.6.0/org/apache/beam/sdk/io/fs/ResourceId.html>, but thus far I have not been able to actually get the GCS ACL. It seems that it is not possible at this time. Assuming there is no clean way to accomplish what I am trying to do in Beam, are there any plans for a GcsIO that would do this? Eric
