> FileBasedCacheManager used by Python's InteractiveRunner does not preserve
> PCoder for elements of a PCollection being cached on disk. I suggest that the
> cache on-disk format to be changed to TFRecords (which are supported by Beam)
> and FileBasedCacheManager would store the desired PCoder for cached
> collections.
> Currently, it is not possible to work with dynamically-generated protocol
> buffer messages in interactive runner mode because of pickling errors.
