Chapter 13. Concurrency Control
Why concurrency control and recovery are necessary in a database system is then discussed. The concept of an atomic transaction and additional concepts related
TicToc: Time Traveling Optimistic Concurrency Control
Previous research has shown that timestamp management is the key scalability bottleneck in concurrency control algorithms. This pre- vents the system from
On Optimistic Methods for Concurrency Control
Most current approaches to concurrency control in database systems rely on locking of data objects as a control mechanism. In this paper two families of
