> Key: BEAM-6670

> Remaining Estimate: 0h
>
> I'm doing approx. 20 JDBC queries against a database and then joining them
> together in a group by. Every single one of these queries does a reshuffle,
> which is sort of useless due to them being fed to a CoGroupByKey immediately
> afterwards.
> Reshuffle by default seems sensible by the principle of least surprise, but
> it would be nice to have a way to disable it when it's not necessary. For
> example a "withReshuffle(boolean)" method.
> This should be an easy addition and I am willing to add this if it sounds
> reasonable enough.
