    Description

      There's not really a lot of reason to store a Columns instance in each row. Retaining it introduces extra costs on every row merge, in both consumed CPU time and heap.

      While working on CASSANDRA-10045 it became apparent this would be very easy to remove, however to avoid scope creep I have filed this as a follow up ticket.
