Subject [jira] [Commented] (CASSANDRA-4415) Add cursor API/auto paging to the native CQL protocol
Date Thu, 29 May 2014 14:05:04 GMT

    [ https://issues.apache.org/jira/browse/CASSANDRA-4415?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14012385#comment-14012385

Shridhar commented on CASSANDRA-4415:
-------------------------------------

I have downloaded Cassandra 2.0.7 and installed. My understanding is that if i run any query
i wont get any time-out exception as like Cassandra 1x versions since auto pagination is done
in Cassandra 2x. But i can still see time-out exception in my Cassandra 2.0.7.
Is that my understanding is wrong or is that am missing anything like configuration.

> 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.
