Q from Olivier - Are the data nodes MySQL servers too ?
No, the data node is handled by a separate process, ndbd, that only manages data.
Q from Olivier: So, what is MySQL Cluster? A MySQL AB product ?
Technically speaking, MySQL Cluster is a storage engine, based on a network distributed database. From a commercial point of view, we refer at MySQL Cluster as a product. We also provide APIs to access to the Cluster database directly, bypassing the MySQL Server and the storage engine architecture.
