"e;THINK."e; In 1914, Thomas J. Watson, Sr. joined the company that was to become IBM, and he brought with him this simple one-word motto. It was an exhortation to all IBM employees, no matter their role, to take care in decision-making and do their jobs with intelligence. "e;THINK"e; soon became an icon, appearing on publications, calendars, and plaques in the offices of many IT and business managers within and outside IBM, and even in The New Yorker magazine cartoons. "e;THINK"e; was a good idea in 1914, and it is a good idea now. "e;Think different."e; More recently, Apple Computer used this slogan in a long-running advertising campaign to revitalize the company's brand, and even more important, to revo- tionize how people think of technology in their daily lives. Instead of saying "e;think differently,"e; suggesting how to think, Apple's slogan used the word "e;different"e; as the object of the verb "e;think,"e; suggesting what to think (as in, "e;think big"e;). The advertising campaign emphasized creativity and creative people, with the implication that Apple's computers uniquely enable innovative solutions and artistic achievements. When I joined Oracle Corporation (then Relational Software Incorporated) back in 1981, database systems incorporating the relational model were a new, emerging technology.

Know how locks work in MySQL and how they relate to transactions. This book explains the major role that locks play in database systems, showing how locks are essential in allowing high-concurrency workloads. You will learn about lock access levels and lock granularities from the user level as well as table locks to record and gap locks. Most importantly, the book covers troubleshooting techniques when locking becomes a pain point. Several of the lock types in MySQL have a duration of a transaction. For this reason, it is important to understand how transactions work. This book covers the basics of transactions as well as transaction isolation levels and how they affect locking. The book is meant to be your go-to resource for solving locking contention and similar problems in high-performance MySQL database applications. Detecting locking issues when they occur is the first key to resolving such issues. MySQL Concurrency provides techniques for detecting locking issues such as contention. The book shows how to analyze locks that are causing contention to see why those locks are in place. A collection of six comprehensive case studies combine locking and transactional theory with realistic lock conflicts. The case studies walk you through the symptoms to look for in order to identify which issue you are facing, the cause of the conflict, its analysis, solution, and how to prevent the issue in the future. What You Will LearnUnderstand which lock types exist in MySQL and how they are usedChoose the best transaction isolation level for a given transactionDetect and analyze lock contention when it occursReduce locking issues in your applicationsResolve deadlocks between transactionsResolve InnoDB record-level locking issuesResolve issues from metadata and schema locksWho This Book Is ForDatabase administrators and SQL developers who are familiar with MySQL and want to gain a better understanding of locking and transactions as well as how to work with them.
