- The Deuteronomy High Performance Transactional Key-Value Store
- The Deuteronomy architecture provides a clean separation of transaction functionality (performed in a transaction component, or TC) from data management functionality (performed in a data component, or DC). In prior work we implemented both a TC and DC that achieved modest performance. More recently we first built a high performance DC (the Bw-tree key value store) that achieves very high performance on modern hardware. The Bw-tree is currently shipping as an indexing and storage layer in a number of Microsoft systems, including Hekaton and DocumentDB. This new DC executes operations more than 100× faster than the DC we previously implemented. Our newly re-implemented TC combined with the our new DC commits more than 1.5 million transactions per second (6 million total operations per second) for a variety of workloads. This demonstrates that Deuteronomy can achieve very high performance overall. Importantly, the resulting Deuteronomy full stack system's data resides on secondary storage and is only cached in main memory, while it has performance on a par with the best main memory systems.
