An intelligent adaptive participant's presumption protocol for atomic commitment in distributed databases

Extending the Intelligent Adaptive Participant's Presumption Protocol to the Multi-Level Distributed Transaction Execution Model

“…That is, the coordinator uses the 2PC part of the ML-iAP 3 discussed in Section 2.2. Thus, with the exception in the way a coordinator decide on which protocol to use with each of its direct descendants, the coordinator's protocol proceeds as in two-level iAP 3 [13].…”

“…Thus, achieving the performance advantages of 1PC protocols whenever possible, on one hand, and the broad applicability of 2PC protocols, on the other. The Intelligent AP 3 (iAP 3 ) extends the (basic) AP 3 [13] by incorporating four advanced features that address and resolve four important issues in the design of atomic commit protocols: two of which enhance efficiency while the other two enhance applicability.…”

“…Therefore, it is a unit of logical work composed of a set of data operations (read and write) [1]. It must follow Atomicity, Consistency, Isolation, and Durability (ACID) property [2].…”

“…To minimize the adverse effects of this overhead on the overall system performance, there is a continuing interest in developing more efficient ACPs and optimizations, albeit for different distributed database system environments with inherently different characteristics. These include main memory databases (e.g., [5]), mobile and ad hoc networks (e.g., [6,7,8] ), real-time databases (e.g., [9,10,11]) and component-based architectures (e.g., [12]); besides traditional distributed database systems (e.g., [3,13]).…”
