Memcache vs MySQL Memory Engine vs MySQL Cluster
http://www.bigdbahead.com/?p=183

Too good to be true… I recently experimented with NDB temporary tables for session of a popular online game. We pushed the cluster very hard, with 10 servers simulating 4 millions active simultaneous game sessions and the cluster handled that very easily. The cluster was large, 24 data nodes (2 per server) and 20 SQL nodes. At full load, the ndbd processes were running at 20% of CPU usage. Even with such a large cluster, the session load would have too large for the disks of the ndb nodes without the use of “set ndb_table_no_logging=1;”.
