Dear MySQL Cluster users,

A new version of MySQL Cluster 7.1 beta has been released and is available from our ftp directory at

ftp://ftp.mysql.com/pub/mysql/download/mysql-5.1.41-ndb-7.1.1-beta.tgz

The Cluster 7.1 beta code base is identical to Cluster 7.0 GA. While maintaining our GA quality throughout all core functionalities we added two of the most requested enhancements as independed features to 7.1 beta:

• ndb$info with SQL level real-time monitoring of Cluster
• an easy-to-use and high performance native Java interface and OpenJPA plug-in

* ndb$info

ndb$info makes cluster status and statistics available on SQL level. Log into the MySQL Server and simply use SQL to retrieve configuration details, memory status or the node status and uptime:

mysql> SELECT * FROM ndbinfo.nodes;
+---------+--------+---------+-------------+
| node_id | uptime | status | start_phase |
+---------+--------+---------+-------------+
|       2 | 45678 | STARTED |           0 |
|       3 | 45676 | STARTED |           0 |
|       4 | 45678 | STARTED |           0 |
|       5 |    312 | STARTED |           0 |
+---------+--------+---------+-------------+
4 rows in set (0.03 sec)

ndb$info is designed to add little to no overhead even for extensive monitoring of Cluster.

* MySQL Cluster Connector for Java

Designed for Java developers, the MySQL Cluster Connector for Java implements an easy-to-use and high performance native Java interface and OpenJPA plug-in. Using the Java Persistence Interface of Cluster/J a primary key lookup is as simple as

Fish e = session.find(Fish.class, 4711);

The OpenJPA for Cluster implementation plugs into Apache OpenJPA and provides native access to Cluster. Many transactions can now be directly executed on Cluster, without the MySQL Server being involved. This allows much faster query execution and higher throughput.

You can read more about Cluster/J and how to use it here:

To learn more about and have the chance to meet the architect and developer behind Cluster/J you might want to attend the webinar. More info here:
