------------------------------------

             Summary: Downgrade Row.columns() to Collection<ColumnDefinition>
                 Key: CASSANDRA-10193
                 URL: https://issues.apache.org/jira/browse/CASSANDRA-10193
             Project: Cassandra
          Issue Type: Improvement
          Components: Core
            Reporter: Benedict
            Assignee: Benedict
            Priority: Minor
             Fix For: 3.0.0 rc1


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.
