Work Description: yifanmai opened a new pull request #12655:
URL: https://github.com/apache/beam/pull/12655
Currently, `PTransformOverride` only supports overriding `PTransform` s that
have a single input. This change adds support for multiple main inputs and side
inputs.
The change introduces a new method
`PTransformOverride.get_replacement_inputs(self, applied_ptransform)` that can
be overridden by end users. This method will be called to get the inputs for
the replacement `PTransform.` The default implementation will return a tuple of
all the main inputs in order, concatenated with the all the side inputs
`PValue` s in order.
