> 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).
