MySQL 5.1 Cluster Testing

Hi,

It has been a while since I last posted. We have been busy testing MySQL Cluster, MySQL Replication and MySQL Cluster Replication. Good news is the serious bugs are getting harder to find. This is allowing us to spend some time automating more testing like configuration and up/down grade testing for example.

The documentation guy for cluster, Jonathan "Jon" Stephens, has been doing great work to expand the Cluster on-line manual. If you have not been out there in a while to review you should have a look.

http://dev.mysql.com/doc/refman/5.1/en/mysql-cluster.html

I feel very positive about this version of the cluster as it has had more hands on testing then ever before. The testing includes: Functional, Negative, Load/Stress, Performance, Recovery, Network Failure, etc...

The new Disk Data will allow customer with huge database to start taking advantage of the reliability and scalability that the cluster offers.

In addition the Cluster Replication opens a whole new use for cluster. This feature adds a few more 9's to the 99.999 up time for services and allows for many different strategies in database design to take place.

One example would be to replicate to another cluster so that data mining and report generation can be done with out putting a load on the main system.

In addition, you could replicate to another site so that if something goes wrong at the main site the secondary site could take over minimizing the companies down time.

I would love to here from the users out there in the world that are using the cluster and have ideas of test they would like to see done, and or want to share how they are using it so we can incorporate that into our testing.

I will attempt to post more often and keep you apprised of our efforts and share any tips or trick I run across that might run across.

Cheers!
