I’ve explored the features of Mysql Cluster 7.2 and 7.3 and now Oracle is coming out with 7.4 with very nice improvements.
This is yet another reason to go for baremetal (softlayer or others) and setup 4 node machine (or more) and enjoy the features of fairly priced or free mysql cluster.
These are the features listed from a Webinar :
- Performance enhancements: MySQL Cluster 7.4 delivers a 50 percent performance improvement over MySQL Cluster 7.3 for Read-Only workloads and 40 percent improvement for Read/Write operations. Performance improvements are available through SQL or any of the native NoSQL APIs supported by MySQL Cluster. New records of 200 Million NoSQL Queries Per Second (QPS) and 2.5 Million SQL QPS were established.
- New geographic redundancy features for high availability across data centers: The latest release provides rollback of any conflicting transactions – enabling full active-active, update-anywhere replication between geographically distant clusters, with applications able to send reads and writes to any site without compromising on consistency.
- Faster online maintenance and recovery operationsincluding the ability to roll out software upgrades as much as 5x faster.
- Enhanced distributed monitoring of memory usage and database operations.
