AI总结：
Shirakami结合长读写事务的多版本视图可串行化和短事务的Silo，实现稳定性能，实验显示其比PostgreSQL快7.9倍，比Shirakami-OCC吞吐量高680倍。
摘要：
Bill-of-materials和电信计费应用需要同时处理短和长的读写事务。最近的研究很少涉及此类变化的工作负载。为了解决这些工作负载，我们提出了一种新的并发控制协议，Shirakami。Shirakami是一种混合协议。第一个协议，Shirakami-LTX，是基于多版本视图可串行化的长读写事务。第二个协议，Shirakami-OCC，是基于Silo的短事务。Shirakami自然地集成了写入保护和基于纪元的同步。它不需要动态协议切换，并提供了稳定的性能。我们实现了Shirakami作为Tsurugi系统的事务处理模块，这是一个生产级的关系数据库系统。实验结果表明，Tsurugi至少比PostgreSQL快7.9倍，而Shirakami-LTX的吞吐量比Shirakami-OCC高680倍。
英文摘要：
Bill-of-materials and telecommunications billing applications need to process both short and long read-write transactions simultaneously. Recent work rarely addresses such evolving workloads. To deal with these workloads, we propose a new concurrency control protocol, Shirakami. Shirakami is a hybrid protocol. The first protocol, Shirakami-LTX, is for long read-write transactions based on multiversion view serializability. The second protocol, Shirakami-OCC, is for short transactions based on Silo. Shirakami naturally integrates them with write-preservation and epoch-based synchronization. It does not require dynamic protocol switching and provides stable performance. We implemented Shirakami as the transaction processing module of the Tsurugi system, which is a production-grade relational database system. The experimental results demonstrated that Tsurugi was at least 7.9x faster than PostgreSQL, and Shirakami-LTX exhibited 680x higher throughput than Shirakami-OCC.
