> 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.
