Benedict commented on CASSANDRA-5019:
-------------------------------------
Major overhaul, so suggested with caution, but why don't we pass a context that
knows what to do with the results, and is furnished with them as they are found
by the CollationController? There's no real need to construct a Row at any
point - in fact it looks like it gets translated straight into a
List<List<ByteBuffer>> at the end anyway.
> Still too much object allocation on reads
