Description

One last improvement I'd like to do on the serialization side is that we currently serialize the SerializationHeader for each partition. That header contains the serialized columns in particular and for range queries, serializing that for every partition is wasted (note that it's only a problem for the messaging protocol as for sstable we only write the header once per sstable).
