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

             Summary: Consider allowing clients to make the Paging State available to users
                 Key: CASSANDRA-7129
                 URL: https://issues.apache.org/jira/browse/CASSANDRA-7129
             Project: Cassandra
          Issue Type: Improvement
          Components: API
            Reporter: Michaël Figuière


This is a follow up to a ticket that has been opened on the DataStax Java Driver JIRA (https://datastax-oss.atlassian.net/browse/JAVA-323).

Currently the Paging State is described as an internal data structure that might change in any upcoming version. As a consequence it isn't safe to make it available to users of the Cassandra Drivers.

It would be and interesting feature to work on making Cassandra safe against all the situation that might happen after unleashing paging states in the wild on the client side: they could end up being included in some web cookies, allowing malicious users to forge some, we might also have some compatibility issues as some paging states might come back to Cassandra after an upgrade of the cluster,...

If the discussion in this ticket turns out to conclude that the paging state SHOULD NOT be made available to users, at least it will be a clarification of something that was mostly implicit (AFAIK) so far.
