> The goal here would be to use a query paging mechanism to the CQL native protocol. Typically the client/server with that would look something like this:
> {noformat}
> C sends query to S.
> S sends N first rows matching the query + flag saying the response is not complete
> C requests the next N rows
> S sends N next rows + flag saying whether there is more
> C requests the next N rows
> ...
> S sends last rows + flag saying there is no more result
> {noformat}
> The clear goal is for user to not have to worry about limiting queries and doing manual paging.
