> We already have a framework for creating new sources for Beam Python SDK - https://github.com/apache/incubator-beam/blob/python-sdk/sdks/python/apache_beam/io/iobase.py#L326
> It would be great if we can add a framework on top of this that encapsulates logic common to sources that are based on files. This framework can include following features that are common to sources based on files.
> (1) glob expansion
> (2) support for new file-systems
> (3) dynamic work rebalancing based on byte offsets
> (4) support for reading compressed files.
> Java SDK has a similar framework and it's available at - https://github.com/apache/incubator-beam/blob/master/sdks/java/core/src/main/java/org/apache/beam/sdk/io/FileBasedSource.java
