Designed for 99.999% Availability

MySQL Cluster Carrier Grade Edition provides a fault tolerant architecture that ensures your company's mission critical applications achieve 99.999% availability. MySQL Cluster CGE automatically and transparently distributes your data across multiple data nodes. MySQL Cluster CGE always ensures an entire system can be safely recovered to a consistent state by using a combination of checkpoints and log files. Redundancy can be achieved at machine level and site level.

Reliability

MySQL Cluster CGE delivers extremely fast failover time with sub-second response so your applications can recover quickly in the event of application, network or hardware failure. MySQL Cluster CGE uses synchronous replication to propagate transaction information to all the appropriate database nodes so applications can automatically fail over to another node while maintaining data consistency. This eliminates the time consuming operation of recreating and replaying log files required by 'Shared-Disk' architectures to fail over successfully.

MySQL Cluster CGE database nodes automatically restart, recover, and dynamically reconfigure themselves in case of failures without having to program advanced features into applications reducing both development and management costs.

Geographic Replication

MySQL Cluster CGE supports asynchronous replication between clusters within the local data center or across a wide area network. This allows organizations to cost-effectively mitigate potential site failures, while simultaneously increasing availability and scalability. Multiple sites can be configured, in active-standby or active-active topologies.
