Subject [jira] [Created] (CASSANDRA-4415) Add cursor API/auto paging to the native CQL protocol
Date Thu, 05 Jul 2012 16:47:33 GMT
Sylvain Lebresne created CASSANDRA-4415:
-------------------------------------------

             Summary: Add cursor API/auto paging to the native CQL protocol
                 Key: CASSANDRA-4415
                 URL: https://issues.apache.org/jira/browse/CASSANDRA-4415
             Project: Cassandra
          Issue Type: New Feature
    Affects Versions: 1.2
            Reporter: Sylvain Lebresne


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.
