Databases are software. I’ve based the second half of a software development career that began in 1978 on this simple idea. If you’ve found this book, chances are you’re willing to at least entertain the possibility that databases and their attendant programmability are worthy of the same rigor and process as the rest of an application. Good for you! It’s a great pleasure for me to join you on this journey,however briefly, via this foreword.

We had several goals in mind for this book. Many of them were derived from think-ing about that mythical perfect MySQL book that none of us had read but that we kept looking for on bookstore shelves. Others came from a lot of experience helping other users put MySQL to work in their environments.

MySQL Cluster is a scalable main memory database management system with high performance and high reliability. The system consists of two parts – the MySQL Server and the NDB Cluster storage engine. This manual describes the NDB Cluster storage engine. The MySQL Server is described in the MySQL Reference Manual. The NDB Cluster can be run integrated with the MySQL Server or as a standalone database server. NDB Cluster synchronously replicates the database on several nodes, making the system withstand software and hardware failures without loss of information. Due to the synchronous replication algorithm, take-over of failed nodes is instantaneous. NDB Cluster is highly configurable...

Acknowledgments I would like to express special thanks to Andy Oram for his continual guidance and encouragement as we worked together on this book. I am particularly grateful to the MySQL development team for their cooperation and active participation in the review. The input I received from Sergei Golubchik was invaluable. His knowledge and vision of the MySQL code and architecture is amazing, as well as his ability to pay attention to detail. At times, as I read his reviews, I would wonder if he possibly got tired of the loads of technical detail and would speed-read past some inaccura- cies or errors. The next moment I saw...
