Yet another 5.1 question - large datasets, disk based, hot plug servers

[Brian Z]

Hello list,

I have been following with great interest the developments in Mysql Cluster. If someone could point me in the right direction for answers or give some insight, I would appreciate it.

Is there a roadmap for release dates, specifically for the 5.1 GA release.

Is there anywhere I can follow development on the hot plug in/out of servers into Cluster? Backing up, plugging in a new storage server, and restoring is not acceptable in our environment just to grow capacity.

Is there somewhere I can find detailed specifications on disk-based NDB? I need to know planned database size limitations, and overhead involved in management of very large datasets.

Our datasets range from a few hundred megabytes, to about 1.3TB with about 10TB data total in our active databases. There's another 1TB of nearline log data which requires extremely high write rates from a cluster of 60 realtime application servers, and high read requirements when reports are run off the logs.

We have 4 quad Xeon 3.66Ghz 16GB ram 2x36GB 10k rpm 6x146GB 15k rpm drives. I need to start migrating some data into a MySQL Cluster due to another db's licencing costs and our old MySQL installations' performance, but the above are all show stoppers until they can be dealt with.

Brian
