论文摘要
在本文中，我们开发了RCC，这是第一个统一且启用RDMA的分布式交易处理框架，支持六个可序列化的并发控制协议：不仅是现在的经典协议，Waitdie和OCC，而且更先进的MVCC和Sundial，甚至Calvin，甚至Calvin，甚至Calvin，确定性并发控制协议。我们的目标是公正地将共同执行环境中的协议与并发控制协议是唯一可更改的组件进行比较。我们专注于使用关键技术的正确和高效的实施，例如共同改进，未偿还的请求和门铃批处理，并具有双面和单面通信原始图。根据RCC，我们获得了任何现有系统无法获得的深刻见解。最重要的是，我们通过单方面和双面原始词来获得每个协议的执行阶段延迟分解，并进行分析以开发更有效的混合实现。我们的结果表明，三种混合设计确实比单方面和双向实现要好17.8％。我们认为，RCC在最先进的情况下是一个重大进步。它既可以提供绩效见解，又可以用作快速原型制定新实施的常见基础架构。
In this paper, we develop RCC, the first unified and comprehensive RDMA-enabled distributed transaction processing framework supporting six serializable concurrency control protocols: not only the classical protocols NOWAIT, WAITDIE, and OCC, but also more advanced MVCC and SUNDIAL, and even CALVIN, the deterministic concurrency control protocol. Our goal is to unbiasedly compare the protocols in a common execution environment with the concurrency control protocol being the only changeable component. We focus on the correct and efficient implementation using key techniques, such as co-routines, outstanding requests, and doorbell batching, with two-sided and one-sided communication primitives. Based on RCC, we get the deep insights that cannot be obtained by any existing systems. Most importantly, we obtain the execution stage latency breakdowns with one-sided and two-sided primitive for each protocol, which are analyzed to develop more efficient hybrid implementations. Our results show that three hybrid designs are indeed better than both one-sided and two-sided implementations by up to 17.8%. We believe that RCC is a significant advance over the state-of-the-art; it can both provide performance insights and be used as the common infrastructure for fast prototyping new implementations.
