DudeTx uses shadowDRAM to decouple the execution of a durable transaction into three fully asynchronous steps. The advantage is that only minimal fences and no memory read instrumentation are required. This design enables an out-of-the-box concurrency control mechanism, transactional memory or fine-grained locks, to be used as an independent component. The evaluation results show that DudeTx adds durability to a software transactional memory system with only 7.4% ∼ 24.6% throughput degradation. Compared to typical existing durable transaction systems, DudeTx provides 1.7× ∼ 4.4× higher throughput. Moreover, DudeTx can be implemented with hardware transactional memory or lock-based concurrency control, leading to a further 1.7× and 3.3× speedup, respectively." -- Sent from: http://www.postgresql-archive.org/PostgreSQL-hackers-f1928748.html
