> CASSANDRA-10193 changed {{BTreeRow}} to not contain an instance of the column definition, but {{AbstractRow.hashCode()}} still uses it to calculate hash. As a result the value returned is always different, breaking any use of {{Row}} as key.
> AFAICS currently unused, needed for tests in CASSANDRA-7019.
