> A secondary index query on a partition key column will, apparently, not return the empty
partitions with static data.
> The following unit test can be used to reproduce the problem.
> {code}
>     public void testIndexOnPartitionKeyWithStaticColumnAndNoRows() throws Throwable
>     {
>         createTable("CREATE TABLE %s (pk1 int, pk2 int, c int, s int static, v int, PRIMARY
KEY((pk1, pk2), c))");
>         createIndex("CREATE INDEX ON %s (pk2)");
>         execute("INSERT INTO %s (pk1, pk2, c, s, v) VALUES (?, ?, ?, ?, ?)", 1, 1, 1,
9, 1);
>         execute("INSERT INTO %s (pk1, pk2, c, s, v) VALUES (?, ?, ?, ?, ?)", 1, 1, 2,
9, 2);
>         execute("INSERT INTO %s (pk1, pk2, s) VALUES (?, ?, ?)", 2, 1, 9);
>         execute("INSERT INTO %s (pk1, pk2, c, s, v) VALUES (?, ?, ?, ?, ?)", 3, 1, 1,
9, 1);
>         assertRows(execute("SELECT * FROM %s WHERE pk2 = ?", 1),
>                    row(1, 1, 1, 9, 1),
>                    row(1, 1, 2, 9, 2),
>                    row(2, 1, null, 9, null), <-- is not returned
>                    row(3, 1, 1, 9, 1));
>     }
> {code}
