Obtaining MySQL Cluster NDB 6.3.  The latest MySQL Cluster NDB 6.3 binaries for supported platforms can be obtained from http://dev.mysql.com/downloads/cluster/.

Note

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

  • Cluster API: Added DUMP code 2514, which provides information about counts of transaction objects per API node. For more information, see DUMP 2514. See also Commands in the MySQL Cluster Management Client. (Bug #15878085)

  • When ndb_restore fails to find a table, it now includes in the error output an NDB API error code giving the reason for the failure. (Bug #16329067)

Bugs Fixed

  • The NDB Error-Reporting Utility (ndb_error_reporter) failed to include the cluster nodes' log files in the archive it produced when the FILE option was set for the parameter LogDestination. (Bug #16765651)

    References: See also: Bug #11752792, Bug #44082.

  • Added the ndb_error_reporter options --connection-timeout, which makes it possible to set a timeout for connecting to nodes, --dry-scp, which disables scp connections to remote hosts, and --skip-nodegroup, which skips all nodes in a given node group. (Bug #16602002)

    References: See also: Bug #11752792, Bug #44082.

  • Attempting to perform additional operations such as ADD COLUMN as part of an ALTER [ONLINE | OFFLINE] TABLE ... RENAME ... statement is not supported, and now fails with an ER_NOT_SUPPORTED_YET error. (Bug #16021021)

  • Purging the binary logs could sometimes cause mysqld to crash. (Bug #15854719)

  • Due to a known issue in the MySQL Server, it is possible to drop the PERFORMANCE_SCHEMA database. (Bug #15831748) In addition, when executed on a MySQL Server acting as a MySQL Cluster SQL node, DROP DATABASE caused this database to be dropped on all SQL nodes in the cluster. Now, when executing a distributed drop of a database, NDB does not delete tables that are local only. This prevents MySQL system databases from being dropped in such cases. (Bug #14798043)

    References: See also: Bug #15831748.

  • ndb_error-reporter did not support the --help option. (Bug #11756666, Bug #48606)

    References: See also: Bug #11752792, Bug #44082.

  • A number of fixes for ndb_error_reporter have been backported from MySQL Cluster NDB 7.0 and later to this NDB 6.3 release, and are listed here:

    • Bug #11764570, Bug #57417: If LogDestination=FILE is included without a file name, use ndb_nodeid_cluster.log as the default.

    • Bug #16765651: Add * to scp command, to include all log files

    • Bug #16602002: Add the --connection-timeout, --skip-nodegroup and --dry-scp options.

      Note

      Since NDB 6.3 does not support the NodeGroup configuration parameter, node groups cannot be queried using ndb_config; use ndb_mgm -e show to get the node groups for the --skip-nodegroup option.

    • Bug #11756666, Bug #48606: Add missing --help option.
