Damn, no CoGrouped[K,V].mapKeys[K1]( fn: (K => K1)@@Bijection ):CoGrouped[K1,V] in @scalding

@avibryant@c_chep@scalding If you keep as a CoGrouped[K1, V] you 'should' be able to join that with another CoGrouped[K1, V2] -
@avibryant@c_chep@scalding If you do that reduce side the shuffles will occur on different types/orderings which would be bad I think. -

@avibryant exactly my concern (in the generalised case; in my practice where K1 is K@@T, ordering is kt.unwrap's ord)@0x138@scalding
