On Transactional Concurrency Control - Goetz Graefe

This Book Contains A Number Of Chapters On Transactional Database Concurrency Control. It Includes Insightful Discussion Of How Traditional Locking Techniques Can Be Improved In Multiple Dimensions, Notably In Lock Scopes (sizes), Lock Modes (increment, Decrement, And More), Lock Durations (late Acquisition, Early Release), And Lock Acquisition Sequence (to Avoid Deadlocks). The Book Takes The Position That Even If Some Of These Improvements Can Be Transferred To Optimistic Concurrency Control, Notably A Fine Granularity Of Concurrency Control With Serializable Transaction Isolation Including Phantom Protection, Pessimistic Concurrency Control Is Categorically Superior To Optimistic Concurrency Control, I.e., Independent Of Application, Workload, Deployment, Hardware, And Software Implementation.
