HyPer is a hybrid online transactional processing (OLTP) and online analytical processing (OLAP) high-performance main memory database system that is optimized for modern hardware. HyPer achieves highest performance—compared to state of the art main memory databases—for both, OLTP (> 100,000 single-threaded TPC-C TX/s on modern commodity hardware) and OLAP (best-of-breed response times), operating simultaneously on the same database.
