----------------------------------------
Summary: Add an IOChannelFactory interface to Python SDK
Key: BEAM-1441
URL: https://issues.apache.org/jira/browse/BEAM-1441
Project: Beam
Issue Type: New Feature
Components: sdk-py
Reporter: Chamikara Jayalath
Based on proposal [1], an IOChannelFactory interface was added to Java SDK [2].
We should add a similar interface to Python SDK and provide proper
implementations for native files, GCS, and other useful formats.
Python SDK currently has a basic ChannelFactory interface [3] which is used by
FileBasedSource [4].
