Review comment:
I think we can make initialization in the field declaration. We needed
this pattern in Python since Python (unlike Java) does not call superclass
constructor by default.

> As discussed in BEAM-673 runners can allocate workers to accomplish their
> work in a better way if they can take into account some hints from the
> transforms, e.g. a source can hint data locality and with this information
> the runner can allocate the workers in an better way, this can also be the
> case with a particular transform that can suggest to the runner to be
> executed in a worker with a specific resource, e.g. GPU.
