This is a bugfix release, fixing recently discovered bugs in the previous MySQL Cluster NDB 6.1 release.
MySQL Cluster NDB 6.1 no longer in development. MySQL Cluster NDB 6.1 (formerly known as “MySQL Cluster Carrier Grade Edition 6.1.x”) is no longer being developed or maintained; if you are using a MySQL Cluster NDB 6.1 release, you should consider upgrading to MySQL Cluster NDB 6.2 or 6.3.
This Beta release incorporates all bugfixes and changes made in the previous MySQL Cluster NDB 6.1 release, as well as all bugfixes and feature changes which were added in mainline MySQL 5.1 through MySQL 5.1.15 (see Section C.1.37, “Changes in MySQL 5.1.15 (25 January 2007)”).
Please refer to our bug database at http://bugs.mysql.com/ for more details about the individual bugs fixed in this version.
Functionality added or changed:
A single cluster can now support up to 255 API nodes, including MySQL servers acting as SQL nodes. See Section 17.1.5.8, “Issues Exclusive to MySQL Cluster”, for more information.
Bugs fixed:
A memory leak could cause problems during a node or cluster shutdown or failure. (Bug#25997)
Cluster API: Disk Data:
A delete and a read performed in the same operation could cause
one or more data nodes to crash. This could occur when the
operation affected more than 5 columns concurrently, or when one
or more of the columns was of the
VARCHAR
type and was stored on
disk.
(Bug#25794)
An element could sometimes be inserted twice into the hash table, causing a data node to crash. (Bug#25286)
