Abstract

In the literature, speculation-based protocols have been proposed to improve the performance of read-only transactions (ROTs) over the existing two-phase locking (2PL) and snapshot isolation(SI)-based protocols. In this paper, we have compared the performance of asynchronous speculation-based protocol with 2PL and SI-based protocols through analytical and simulation methods. The results show that asynchronous speculation-based protocol improves the performance over 2PL and SI-based protocols.
