> Some DoFn based IOs like JdbcIO and RedisIO rely on the Reparallelize
> transform,
> a combination of a an empty PCollectionView and Reshuffle to force the
> materialization and reparallelize a PCollection. The idea of this issue is to
> extract this transform and expose it as part of the internal Reshuffle
> transform to avoid repeating the code for transforms (notably IOs) that
> require
> to reparallelize its output.
