Nanu is right ,
MySQL's native cluster has two fatal problems.
1) application limitation
2) performance degrade in certain scenarios
Consult the MySQL Cluster mailing list, there are dozens of similar questions concern it.
Although Oracle RAC has blemish in current design but it is still the strongest SSI Database Cluster of the world, especially upon x86 platform.
(DB2 EEE has more scalable solution on MMP system).
I hope MySQL AB's product team can utilize faster interconnect technology such as infiniband to scale up IO throughput and low the latency as much as possible. (just like digital did on TruCluster with memory channel). To create an individual "Cluster Layer" is another solution to overcome the application limitation.
Till now, i'll never choose mysql's native cluster in my production environment. Although they has a pretty strong support team and considerable service price.
