MySQL Cluster 7.4.8 has been released
Dear MySQL Users, MySQL Cluster 7.4.8 (General Availability) is a new release for MySQL Cluster 7.4. MySQL Cluster is the distributed, shared-nothing variant of MySQL. This storage engine provides: - In-Memory storage - Real-time performance (with optional checkpointing to disk) - Transparent Auto-Sharding - Read & write scalability - Active-Active/Multi-Master geographic replication - 99.999% High Availability with no single point of failure and on-line maintenance - NoSQL and SQL APIs (including C++, Java, http, Memcached and JavaScript/Node.js) MySQL Cluster 7.4 makes significant advances in performance; operational efficiency (such as enhanced reporting and faster restarts and upgrades) and conflict detection and resolution for active-active replication between MySQL Clusters. MySQL Cluster 7.4.8 DMR can be downloaded from the "Development Releases" tab at http://www.mysql.com/downloads/cluster/ where you will also find Quick Start guides to help you get your first MySQL Cluster database up and running. The release notes are available from http://dev.mysql.com/doc/relnotes/mysql-cluster/7.4/en/index.html MySQL Cluster enables users to meet the database challenges of next generation web, cloud, and communications services with uncompromising scalability, uptime and agility. As with any other pre-production release, caution should be taken when installing on production level systems or systems with critical data. More information on the Development Milestone Release process can be found at http://dev.mysql.com/doc/mysql-development-cycle/en/development-milestone-releases.html More details can be found at http://www.mysql.com/products/cluster/ Enjoy ! Changes in MySQL Cluster NDB 7.4.8 (5.6.27-ndb-7.4.8 2015-10-16) MySQL Cluster NDB 7.4.8 is a new release of MySQL Cluster 7.4, based on MySQL Server 5.6 and including features in version 7.4 of the NDB storage engine, as well as fixing recently discovered bugs in previous MySQL Cluster releases. Obtaining MySQL Cluster NDB 7.4. MySQL Cluster NDB 7.4 source code and binaries can be obtained from http://dev.mysql.com/downloads/cluster/. For an overview of changes made in MySQL Cluster NDB 7.4, see MySQL Cluster Development in MySQL Cluster NDB 7.4 (http://dev.mysql.com/doc/refman/5.6/en/mysql-cluster-develop ment-5-6-ndb-7-4.html). 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 5.6 through MySQL 5.6.27 (see Changes in MySQL 5.6.27 (2015-09-30) (http://dev.mysql.com/doc/relnotes/mysql/5.6/en/news-5-6-27.h tml)). Functionality Added or Changed * Important Change; Cluster Replication: Added the create_old_temporals server system variable to compliment the system variables avoid_temporal_upgrade and show_old_temporals introduced in MySQL 5.6.24 and available in MySQL Cluster beginning with NDB 7.3.9 and NDB 7.4.6. Enabling create_old_temporals causes mysqld to use the storage format employed prior to MySQL 5.6.4 when creating any DATE, DATETIME, or TIMESTAMP column---that is, the column is created without any support for fractional seconds. create_old_temporals is disabled by default. The system variable is read-only; to enable the use of pre-5.6.4 temporal types, set the equivalent option (--create-old-temporals) on the command line, or in an option file read by the MySQL server. create_old_temporals is available only in MySQL Cluster; it is not supported in the standard MySQL 5.6 server. It is intended to facilitate upgrades from MySQL Cluster NDB 7.2 to MySQL Cluster NDB 7.3 and 7.4, after which table columns of the affected types can be upgraded to the new storage format. create_old_temporals is deprecated and scheduled for removal in a future version of MySQL Cluster. avoid_temporal_upgrade must also be enabled for this feature to work properly. You should also enable show_old_temporals as well. For more information, see the descriptions of these variables.
