craig mcmillan commented on CASSANDRA-9928:
-------------------------------------------

currently i achieve this function by manually concatenating the extra keys i want in the MV into a single text key - it's roughly workable, but timeuuids can no longer be used to provide ordering, since they don't sort lexically

[~thobbs] solution would formalize and improve upon what i, and presumably many others, are already having to do ?

> Currently we don't allow > 1 non primary key from the base table in a MV primary key.  We should remove this restriction assuming we continue filtering out nulls.  With allowing nulls in the MV columns there are a lot of multiplicative implications we need to think through.
