High-performance transaction processing in SAP HANA

Modern enterprise applications are currently undergoing a complete paradigm shift away from tradi-tional transactional processing to combined analytical and transactional processing. This challenge of combining two opposing query types in a single database management system results in additional re-quirements for transaction management as well. In this paper, we discuss our approach to achieve high throughput for transactional query processing while allowing concurrent analytical queries. We present our approach to distributed snapshot isolation and optimized two-phase commit protocols.
