Subject [jira] [Commented] (CASSANDRA-10220) Memtables do not handle column changes for their PartitionColumns

Sylvain Lebresne commented on CASSANDRA-10220:
----------------------------------------------

I'm pretty certain CASSANDRA-10169 is a manifestation of this, and I'm keen on getting that
fix for beta2 so [~benedict], unless you've already started working on this already, mind
if I mark this a duplicate of CASSANDRA-10169 (or the other way around, whatever) and give
it a quick shot?

> 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.
