Server bottlenecks and failures are a fact of life in any database deployment, but they don't have to bring everything to a halt. This practical book explains replication, cluster, and monitoring features that can help protect your MySQL system from outages, whether it's running on hardware, virtual machines, or in the cloud.
Written by engineers who designed many of the tools covered, this book reveals undocumented or hard-to-find aspects of MySQL reliability and high availability--knowledge that's essential for any organization using this database system. This second edition describes extensive changes to MySQL tools. Versions up to 5.5 are covered, along with several 5.6 features.
- Learn replication fundamentals, including use of the binary log and MySQL Replicant Library
- Handle failing components through redundancy
- Scale out to manage read-load increases, and use data sharding to handle large databases and write-load increases
- Store and replicate data on individual nodes with MySQL Cluster
- Monitor database activity and performance, and major operating system parameters
- Keep track of masters and slaves, and deal with failures and restarts, corruption, and other incidents
- Examine tools including MySQL Enterprise Monitor, MySQL Utilities, and GTIDs
Dr. Charles A Bell is a Senior Software Engineer at Oracle. He iscurrently the lead developer for backup and a member of the MySQLBackup and Replication team. He lives in a small town in ruralVirginia with his loving wife. He received his Doctor of Philosophy inEngineering from Virginia Commonwealth University in 2005. Hisresearch interests include database systems, versioning systems,semantic web, and agile software development.
Dr. Mats Kindahl is a senior software developer working on the MySQLserver. He is the main architect and implementor of MySQL's row-basedreplication and is responsible for strategic development ofreplication, reengineering, and the plugin architecture. Beforestarting at MySQL, he did research in formal methods, programanalysis, and distributed systems, the area where he earned hisdoctoral degree in computer science. He has also spent many yearsdeveloping C/C++ compilers and knows more programming languages thanhe has fingers.
Dr. Lars Thalmann is the development manager for MySQL replication andbackup. He is responsible for the strategy and development of thesefeatures and leads the corresponding engineering teams. Thalmann hasworked with MySQL development since 2001, when he was a softwaredeveloper working on MySQL Cluster. More recently, he has driven thecreation and development of the MySQL backup feature, has guided theevolution of MySQL replication since 2004, and has been a key playerin the development of MySQL Cluster replication. Thalmann holds adoctorate in Computer Science from Uppsala University, Sweden.
