------------------------------------
Summary: Create a transform to assign an index when reading data
from built in I/O transforms
Key: BEAM-7692
URL: https://issues.apache.org/jira/browse/BEAM-7692
Project: Beam
Issue Type: New Feature
Components: io-ideas
Affects Versions: 2.13.0
Reporter: SAILOKESH DIVI
As a beam user
when using any of the existing beams I/O transforms
I would like to add an index to each line read as part of the transform.
As spark has zipWithIndex to assign an index when reading files with the beam
being abstraction layer for may runners. I would expect this feature should be
added to beam
