[jira] [Commented] (CASSANDRA-15201) LegacyLayout does not handle paging states that cross a collection column

    [ https://issues.apache.org/jira/browse/CASSANDRA-15201?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16878730#comment-16878730 ] 

Benedict commented on CASSANDRA-15201:
--------------------------------------

On second thoughts, the dtest is of dubious value without a proper client connection to the old node, which we don't currently have very nice tooling for.  Perhaps we can follow-up, but I've removed the dtest for now.

> {{LegacyLayout.decodeBound}} assumes there is only a single extra component, referring to a column name.  In fact an encoded page boundary may include a collection column, and this occurs as a matter of course when paging a table whose last column is a collection.
