Not exactly sure what you are asking here, but one advantage is that 4.1.12 is the only cluster supported in production until 5.0 ships.

The cluster does consume more memory then a conventional database, but if you where to extend it to three or more systems, then you could loss x numbers of systems and still be processing data. High Availability (HA) is the biggest advantage to MySQL Cluster solution.

Hope this helps,

Hi,

I am studying mysql-cluster. I installed and tested MySQL-max 4.1.12, everything is fine. I used mysql storage nodes and SQL API nodes in the same machine and also a management server like the following article. http://dev.mysql.com/tech-resources/articles/mysql-cluster-for-two- servers.h tml . But I couldn't see much advantages in mysql cluster. If you think of a cluster you should have much more advantages. Such as in 4.1 series performance slows down in cluster than standalone version. It uses much more memory because of the IndexMemory and DataMemory identifiers. What is the advantage of this 4.1 series mysql?

I looked at the features of 5 series and they look great. Do you recommend the beta version? Have you used in production servers?

Thanks for any advice.
