Benchmarking is an essential aspect of any database management system (DBMS) effort. Despite several recent advancements, such as pre-configured cloud database images and database-as-a-service (DBaaS) offerings, the deployment of a comprehensive testing platform with a diverse set of datasets and workloads is still far from being trivial. In many cases,

Scheduling online repartitioning in OLTP systems
Proceedings of the Middleware Industry Track, 2014Previous studies on automatic database partitioning mostly focus on optimizing the (re)partitioning scheme for a given database and its query workload, while overseeing the problem about how to efficiently deploy the partition scheme onto the database system, which is, however, often non-trivial and challenging, especially in a distributed OLTP system ...

System optimization for OLTP workloads
IEEE Micro, 1999Major performance enhancements in large commercial systems are best achieved when advances in hardware technology are matched with advances in software technology. This article connects recent AS/400 hardware advances with the corresponding approaches used to tune the system performance for large online transaction processing (OLTP) workloads.

Pentium MPP for OLTP applications
Proceedings of the Twenty-Eighth Annual Hawaii International Conference on System Sciences, 2002The paper describes a multi-Pentium architecture with a hierarchical memory and an I/O bus subsystem. On a board-level, this architecture achieves a very high-level of integration, by accommodating 8 Pentium processors with up to 2 Gigabytes of RAM. This hierarchical architecture has been extended to support multiple boards in a single cabinet as well ...

Performance of OLTP via Intelligent Scheduling
2018 IEEE 34th International Conference on Data Engineering (ICDE), 2018Current architectures for main-memory online transaction processing (OLTP) database management systems (DBMS) typically use random scheduling to assign transactions to threads. This approach achieves uniform load across threads but it ignores the likelihood of conflicts between transactions.

On scalable net modeling of OLTP
Proceedings of 5th International Workshop on Petri Nets and Performance Models, 2002Practical experiments with the net modeling of OLTP (online transaction processing) applications are discussed. The goal was to propose a convenient and flexible model that would be easy to modify with respect to different scheduling algorithms, number of processors, and disks.

Perhaps the most anticipated new feature in SQL Server 2014 is the In-Memory OLTP database engine component. As its name implies, this new component works with memory-resident data. Current OLTP workloads, which read the pages from disk, need to take and release locks and latches, and they need to wait for log writes to be performed. In-Memory OLTP was

Performance Characters of OLTP in CMP
Journal of Convergence Information Technology, 2011On-Line Transaction Processing (OLTP) workload is an important application in commercial service domain. Chip multiprocessor (CMP) is main stream of processor development. Performance characters of OLTP in CMP become a crucial benchmark for design and performance analysis of CMP server system.

This introductory chapter explains the importance of in-memory databases and the problems they address. It provides an overview of the Microsoft In-Memory OLTP implementation (code name Hekaton) and its design goals. Finally, this chapter discusses the high-level architecture of the In-Memory OLTP Engine and how it is integrated into SQL Server.
