Dear MySQL Cluster users,

A new version of MySQL Cluster 7.1 beta has been released and is =
=20
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 =
=20
maintaining our GA quality throughout all core functionalities we =
=20
added two of the most requested enhancements as independed features t=
o =20
7.1 beta:

=09=95 ndb$info with SQL level real-time monitoring of Cluster
=09=95 an easy-to-use and high performance native Java interface and =
=20
OpenJPA plug-in


* ndb$info

ndb$info makes cluster status and statistics available on SQL level. =
=20
Log into the MySQL Server and simply use SQL to retrieve configuratio=
n =20
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 =
=20
monitoring of Cluster.


* MySQL Cluster Connector for Java

Designed for Java developers, the MySQL Cluster Connector for Java =
=20
implements an easy-to-use and high performance native Java interface =
=20
and OpenJPA plug-in. Using the Java Persistence Interface of Cluster/=
J =20
a primary key lookup is as simple as

  Fish e =3D session.find(Fish.class, 4711);

The OpenJPA for Cluster implementation plugs into Apache OpenJPA and =
=20
provides native access to Cluster. Many transactions can now be =20
directly executed on Cluster, without the MySQL Server being involved=
. =20
This allows much faster query execution and higher throughput.

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

er_14.html

To learn more about and have the chance to meet the architect and =
=20
developer behind Cluster/J you might want to attend the webinar. More=
