Real-time atomic transaction processing using multi-invariant data structure

Many multiple server systems are now being used for heavily accessed web services. Performance, availability, and real-time transaction processing are important requirements for many of these applications. In this paper, we apply the multi-invariant data structure (MIDS) concept for real-time transaction processing. We used the MIDS scheme to develop a highly available, reliable, real-time transaction processing algorithm. We show that with very little overhead compared to the two-phase commit protocol, we achieve non-blocking atomic transaction processing. Also, the algorithm is suitable for real-time processing since a task can be preempted at any point of execution without expensive recovery procedure.
