--------------------------------------------------------------

Thanks. I've ninja fixed what was an obvious rebase error, that I should have never made (but should have been caught by CI. GTK it definitely will be post CASSANDRA-9673 (it's also possible I missed another new non-flakey dtest failure when checking))

> 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).
