Transaction processing using thread-to-metadata

Abstract

In the distributed transactional database systems, there are a large number of concurrent transactions. Each transaction independently executes on a separate thread this is known as thread-to-transaction. The lock manager is hence responsible for maintaining isolation between concurrently-executing transactions, which takes more time from the total time of the execution. In this paper we present a system that improves the response time by using thread-to-metadata policy instead of using thread-to-transaction policy. The system consists of two modules: (a) Transaction Module, and (b) Data Module. The system minimizes the interaction with the lock manager and maintains all the ACID properties of the transactions. We also present experimental results that show how thread-to-metadata policy improves the response time.
