---------------------------------------
Summary: Update filebasedsource to support compressed files
Key: BEAM-577
URL: https://issues.apache.org/jira/browse/BEAM-577
Project: Beam
Issue Type: Improvement
Components: sdk-py
Reporter: Chamikara Jayalath
Assignee: Frances Perry
FileBasedSource framework [1] should be updated to properly read compressed
files.
One possible way to do this might be to update FileBasedSource.open_file() [2]
to return a CompressedFile [3].
Similar to Java implementation, we may not be able to support dynamic work
rebalancing for compressed files.
