Subject [jira] [Created] (CASSANDRA-11208) Paging is broken for IN queries
Date Mon, 22 Feb 2016 20:48:18 GMT
Benjamin Lerer created CASSANDRA-11208:

             Summary: Paging is broken for IN queries
                 Key: CASSANDRA-11208
             Project: Cassandra
          Issue Type: Bug
          Components: CQL
            Reporter: Benjamin Lerer
            Assignee: Benjamin Lerer

If the number of selected row is greater than the page size, C* will return some duplicates.

The problem can be reproduced with the java driver using the following code:
       session = cluster.connect();
       session.execute("CREATE KEYSPACE IF NOT EXISTS test WITH REPLICATION = {'class' : 'SimpleStrategy',
'replication_factor' : '1'}");
       session.execute("USE test");
       session.execute("DROP TABLE IF EXISTS test");
       session.execute("CREATE TABLE test (rc int, pk int, PRIMARY KEY (pk))");

       for (int i = 0; i < 5; i++)
           session.execute("INSERT INTO test (pk, rc) VALUES (?, ?);", i, i);

       ResultSet rs = session.execute(session.newSimpleStatement("SELECT * FROM test WHERE
 pk IN (1, 2, 3)").setFetchSize(2));
