public PCollection<byte[]> expand(PBegin input)
PTransformPTransform should be expanded on the given
InputT.
NOTE: This method should not be called directly. Instead apply the PTransform should
be applied to the InputT using the apply method.
Composite transforms, which are defined in terms of other transforms, should return the output of one of the composed transforms. Non-composite transforms, which do not apply any transforms internally, should return a new unbound output and register evaluators (via backend-specific registration methods).

PTransformPTransform (not including the names of any
enclosing PTransforms).
By default, returns the base name of this PTransform's class.
The caller is responsible for ensuring that names of applied PTransforms are unique,
e.g., by adding a uniquifying suffix when needed.
