Description:
The format of ndbinfo.memoryusage changed shortly before GA. The documentation at http://dev.mysql.com/doc/mysql-cluster-excerpt/5.1/en/mysql-cluster-ndbinfo-memoryusage.ht... still describes the original format. The real view now looks like:

mysql> select * from memoryusage;
+---------+--------------+--------+------------+-----------+-------------+
| node_id | memory_type  | used   | used_pages | total     | total_pages |
+---------+--------------+--------+------------+-----------+-------------+
|       3 | Data memory  | 917504 |         28 | 104857600 |        3200 |
|       3 | Index memory | 221184 |         27 |  11010048 |        1344 |
|       4 | Data memory  | 917504 |         28 | 104857600 |        3200 |
|       4 | Index memory | 221184 |         27 |  11010048 |        1344 |
+---------+--------------+--------+------------+-----------+-------------+

How to repeat:
mysql> select * from ndbinfo.memoryusage;

Suggested fix:
Make documentation reflect the new implementation.

Was this an intentional change? If not, it's a Server bug and needs to be fixed.

I believe that the implementation change was intentional. It was expected that the units would be changed to bytes, I hadn't realised that it would also have new columns for the information as pages but I think that it's useful (partly because the smaller numbers are easier to compare).

Corrected category/lead.

Thank you for your bug report. This issue has been addressed in the documentation. The updated documentation will appear on our website shortly, and will be included in the next release of the relevant products.
