---------------------------------------------
Summary: Add option to return filename from ReadAll transforms
Key: BEAM-12665
URL: https://issues.apache.org/jira/browse/BEAM-12665
Project: Beam
Issue Type: New Feature
Components: io-py-common
Reporter: Inigo San Jose Visiers
When using ReadAll transforms (as `ReadAllFromText` and similar), it would be
great to add the option to also return the filename.
This would help with an use case of reading multiple files that are not known
at launch time and perform aggregations by file
