Jonathan Ellis commented on CASSANDRA-10220:
--------------------------------------------

Is this a correctness issue or just technical debt?

> There are a couple of inherited issues around the {{PartitionColumns}} in {{AbstractBTreePartition}}.
Firstly, we do not always return these columns, but sometimes the metadata columns. Secondly,
the columns cannot be updated with new columns, and the metadata columns will not show dropped
columns. This should most likely be moved into the {{Holder}}, and updated along with any
other updates.
