> As discovered by [~Stefania] in CASSANDRA-12423, our use of {{ColumnIdentifier.internedInstances}} to map byte buffer column names to column identifiers is incorrect. It's possible for two non-equal {{ColumnIdentifier}} instances to have the same {{ByteBuffer}} as raw name, and yet different text representations, due to different column name types, leading to hard to debug correctness issues.
> Should either amend the map to have the type as part of the key, or limit the use of that map.
