MySQL Cluster NDB 7.2.25 is a new release of MySQL Cluster, incorporating new features in the NDB storage engine, and fixing recently discovered bugs in previous MySQL Cluster NDB 7.2 development releases.
Obtaining MySQL Cluster NDB 7.2. MySQL Cluster NDB 7.2 source code and binaries can be obtained from http://dev.mysql.com/downloads/cluster/.
This release also incorporates all bugfixes and changes made in previous MySQL Cluster releases, as well as all bugfixes and feature changes which were added in mainline MySQL 5.5 through MySQL 5.5.50 (see Changes in MySQL 5.5.50 (2016-06-02) (http://dev.mysql.com/doc/relnotes/mysql/5.5/en/news-5-5-50.html)).
* Incompatible Change: When the data nodes are only partially connected to the API nodes, a node used for a pushdown join may get its request from a transaction coordinator on a different node, without (yet) being connected to the API node itself. In such cases, the NodeInfo object for the requesting API node contained no valid info about the software version of the API node, which caused the DBSPJ block to assume (incorrectly) when aborting to assume that the API node used NDB version 7.2.4 or earlier, requiring the use of a backward compatability mode to be used during query abort which sent a node failure error instead of the real error causing the abort. Now, whenever this situation occurs, it is assumed that, if the NDB software version is not yet available, the API node version is greater than 7.2.4. (Bug #23049170)
