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

             Summary: Paging changes to 2.1/2.2 for backward compatibilty with 3.0
                 Key: CASSANDRA-9849
                 URL: https://issues.apache.org/jira/browse/CASSANDRA-9849
             Project: Cassandra
          Issue Type: Bug
            Reporter: Sylvain Lebresne
            Assignee: Tyler Hobbs
             Fix For: 2.1.x, 2.2.x


Quoting [~thobbs] from CASSANDRA-9704:

I forgot to attach a patch for the required 2.1/2.2 changes as well. Basically, when paging
in 2.x, our check to see if a new page contains the same row that the previous page ended
on looks for an exact cell name match. This is fine in 2.x because we will return partial
rows at the end of the page (just the row marker cell). However, in 3.0, we always return
full rows. While we could make some very hacky changes to 3.0 to enable returning a partial
row at the end of the page, this seems like the cleanest solution.
