MySQL Clustering with NDB

Jeremy has posted a lot of interesting information last week from Orlando including notes from the MySQL Cluster talk at this years MySQL user conference.

First we're seeing an overview of the NDB architecture. If you've never seen it before, think "Oracle RAC without shared storage" and you're 95% of the way there.

The press release doesn't get into many details, but some of the follow up comments about the memory requirements on Jeremy's post are rather interesting. MySQL Storage Engine Architecture, Part 1: An Overview covers the in memory requirement for the NDB Cluster Storage engine.
