So yesterday I presented my findings on MySQL Cluster (ndbd) and Drupal.
I`ll be writing them out in a more detailed document some day soon ..
But the short summary is that MySQL-Cluster and Drupal are not a good fit.
One has to realise that MySQL cluster isn't always a good solution and that every problem has it's own solutions. The nature of the tables of Drupal means that you need enormous amounts of memory.
I was a bit afraid that the present MySQL crowd woudln't really appreciate my findings, however I was wrong I got some good feedback from the present MySQL crowd , they too seem to want to promote the idea that Cluster is not a fit for every problem, and they were great help in answering some of the audience questions.
