>                 Key: BEAM-2643
>                 URL:
>             Project: Beam
>          Issue Type: New Feature
>          Components: sdk-py
>            Reporter: Chamikara Jayalath
> Java SDK now has TextIO.read_all() API that allows reading a massive number of files
by moving from using the BoundedSource API (which may perform expensive source operations
on the control plane) to using ParDo operations.
> This API should be added for Python SDK as well.
> This form of reading files does not support dynamic work rebalancing for now. But this
should not matter much when reading a massive number of relatively small files. In the future
this API can support dynamic work rebalancing through Splittable DoFn.
