Work Description: iemejia commented on issue #11406: [BEAM-9748] Move
Reparallelize transform to Reshuffle
URL: https://github.com/apache/beam/pull/11406#issuecomment-613144797
> Why do we want to do this over Reshuffle.viaRandomKeys which should get us
the output parallelization we want?
I think that's the case, maybe @jkff who created that code may confirm.
There seems to be some more details in the implementation choice in the
original ticket [BEAM-2803](https://issues.apache.org/jira/browse/BEAM-2803)

> 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.
