[jira] [Closed] (BEAM-730) Remove Reshuffle transform in favor of Redistribute.byKey()

     [ https://issues.apache.org/jira/browse/BEAM-730?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Eugene Kirpichov closed BEAM-730.
---------------------------------
       Resolution: Won't Fix
    Fix Version/s: Not applicable

We have Reshuffle.viaRandomKey() for one case, and RequiresStableInput annotation for another (not implemented fully yet) and no substantial progress being made other than that. Discussions about Redistribute ended in concluding that there's no single transform to be implemented here.

> https://github.com/apache/incubator-beam/pull/1036 introduces a Redistribute transform which is a superset of Reshuffle. Reshuffle is an internal implementation detail transform, while Redistribute is generally useful. The current bug is to remove Reshuffle or hide it from users to reduce confusion.
