Performance Issues in Scheduling of Real-Time Transactions

The multi-site real-time transactional data-analysis based applications and the underlying research efforts to improve the performance of such applications have got renewed attention by researchers in the last four years. It reveals that the current scenario possesses numerous unanswered and truly relevant issues and challenges requiring a multi-disciplinary research approach to work on and solve the core database transaction processing related issues. Our focus is to cover most of the issues and challenges with transaction scheduling algorithms in one place to put out the current research status. At a high level, the domains covered are-real-time priority assignment heuristics, real-time concurrency control protocols, and real-time commit processing. The article indeed guides towards the immediate-future directions requiring actions/ efforts by the modern data-driven research community.
