SQL Server Concurrency
Transactions are at the heart of concurrency. I explain their ACID properties, the transaction isolation levels that dictate acceptable behaviors when multiple transactions access the same data simultaneously, and SQL Server's optimistic and pessimistic models for mediating concurrent access.
Pessimistic concurrency, SQL Server's default, uses locks to avoid concurrency problems. I explain all the different locks and their compatibility. I show how to control locking with hints and bound connections, and how to troubleshoot excessive blocking and deadlocking.
Optimistic concurrency uses row versions to support concurrency. I explain how row versioning works, cover SQL Server's two snapshot-based isolation levels and offer troubleshooting tips for issues such as update conflicts.
Your application can have world-class indexes and queries, but they won't help you if you can't get your data because another application has it locked. That's why every DBA and developer must understand SQL Server concurrency, and how to troubleshoot any issues. I hope my book helps!
