MySQL Cluster NDB 7.1.23 is a new release of MySQL Cluster, incorporating new features in the NDBCLUSTER storage engine and fixing recently discovered bugs in previous MySQL Cluster NDB 7.1 releases.

Obtaining MySQL Cluster NDB 7.1. The latest MySQL Cluster NDB 7.1 binaries for supported platforms can be obtained from http://dev.mysql.com/downloads/cluster/. Source code for the latest MySQL Cluster NDB 7.1 release can be obtained from the same location. You can also access the MySQL Cluster NDB 7.1 development source tree at https://code.launchpad.net/~mysql/mysql-server/mysql-cluster-7.1.

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 5.1 through MySQL 5.1.63 (see Changes in MySQL 5.1.63 (2012-05-07)).

Bugs Fixed

If the Transaction Coordinator aborted a transaction in the “prepared” state, this could cause a resource leak. (Bug #14208924)
When attempting to connect using a socket with a timeout, it was possible (if the timeout was exceeded) for the socket not to be set back to blocking. (Bug #14107173)
When an NDB table was created during a data node restart, the operation was rolled back in the NDB engine, but not on the SQL node where it was executed. This was due to the table .FRM files not being cleaned up following the operation that was rolled back by NDB. Now in such cases these files are removed. (Bug #13824846)
In some circumstances, transactions could be lost during an online upgrade. (Bug #13834481)
Attempting to add both a column and an index on that column in the same online ALTER TABLE statement caused mysqld to fail. Although this issue affected only the mysqld shipped with MySQL Cluster, the table named in the ALTER TABLE could use any storage engine for which online operations are supported. (Bug #12755722)
Cluster API: When an NDB API application called NdbScanOperation::nextResult() again after the previous call had returned end-of-file (return code 1), a transaction object was leaked. Now when this happens, NDB returns error code 4210 (Ndb sent more info than length specified); previouslyu in such cases, -1 was returned. In addition, the extra transaction object associated with the scan is freed, by returning it to the transaction coordinator's idle list. (Bug #11748194)
