Subject [jira] [Created] (CASSANDRA-11669) RangeName queries might not return all the results
Date Wed, 27 Apr 2016 07:53:13 GMT
Benjamin Lerer created CASSANDRA-11669:
------------------------------------------

             Summary: RangeName queries might not return all the results
                 Key: CASSANDRA-11669
                 URL: https://issues.apache.org/jira/browse/CASSANDRA-11669
             Project: Cassandra
          Issue Type: Bug
            Reporter: Benjamin Lerer
            Assignee: Benjamin Lerer


It seems that if a page end in the middle of a partition the remaining rows of the partition
will never be returned.

The problem can be reproduced using the java driver with the following code:
{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 IF NOT EXISTS test (a int, b int, c int, d int, PRIMARY
KEY(a, b, c))");

        PreparedStatement prepare = session.prepare("INSERT INTO test (a, b, c, d) VALUES
(?, ?, ?, ?);");
        for (int i = 1; i < 4; i++)
            for (int j = 1; j < 5; j++)
                for (int k = 1; k < 5; k++)
                session.execute(prepare.bind(i, j, k, i + j));

        ResultSet rs = session.execute(session.newSimpleStatement("SELECT * FROM test WHERE
b = 1 and c IN (1, 2, 3) ALLOW FILTERING")
                                              .setFetchSize(4));
        for (Row row : rs)
        {
            System.out.println(row); // Only one row will be returned for partition 2 instead
of 3
        }
{code}
