Subject [jira] [Created] (BEAM-778) Make fileio._CompressedFile seekable.

---------------------------------------

             Summary: Make fileio._CompressedFile seekable.
                 Key: BEAM-778
                 URL: https://issues.apache.org/jira/browse/BEAM-778
             Project: Beam
          Issue Type: Improvement
          Components: sdk-py
            Reporter: Chamikara Jayalath
             Fix For: Not applicable


We have a TODO to make fileio._CompressedFile seekable.
https://github.com/apache/incubator-beam/blob/python-sdk/sdks/python/apache_beam/io/fileio.py#L692

Without this, compressed file objects produce for FileBasedSource implementations may not
be able to use libraries that utilize methods seek() and tell().

For example tarfile.open().
