> As discussed in CASSANDRA-6694, to reduce temporary garbage generation we should minimise
the incidence of CellName component extraction. The biggest win will be to perform comparisons
on Cell where possible, instead of CellName, so that Native*Cell can use its extra information
to avoid creating any ByteBuffer objects
