Performance Improvement in Optimistic Concurrency Control Mechanism of Distributed Databases
The main aim of the paper is to improve the performance of optimistic concurrency control mechanism in distributed databases. The original approach of optimistic concurrency with respect to the validation technique, the treatment of long transactions and the problem of starvation. In this paper, design alternatives of the validation phase are considered which not only avoid these disadvantages but additionally improve the performance of the original approach. Very promising is a new validation technique which especially supports read-transactions, therefore, decreasing the number of backups substantially. An adaptation of the new optimistic concurrency control schemes to a distributed environment is presented. The proposed algorithm is deadlock free and offers high parallelism.
