An optimized concurrency control algorithm for transaction processing

Abstract

The focus of this paper is to propose a concurrency control scheme, named Two Phase Integrated Concurrency Control (2-PICC) which can meet the response time requirement under the concurrency level anticipated for future TP systems and provide better performance than any existing concurrency control scheme for virtually all data and hardware contention level. This concurrency control scheme shares the desirable properties of existing concurrency schemes such as the deadlock-free property of OCC, and the transaction-starvation-free property of locking-based concurrency schemes.<>
