Geo-Replicated Transactions in 1.5RTT
Explore a groundbreaking approach to geo-replicated transactions in distributed systems through this 37-minute conference talk from Strange Loop. Dive into the innovative Consus key-value store, which introduces a novel commit protocol capable of executing fully general transactions in just 1.5 round-trip times. Learn how this masterless, active-active system overcomes traditional latency bottlenecks in geo-replicated databases. Gain insights into the motivation, design, and deep technical details of the Consus commit protocol, including its advantages over two-phase commit. Understand the background of distributed systems primitives and grasp the protocol's contributions. Follow along as the speaker covers topics such as geo-replication techniques, stored procedures, commit protocol assumptions, Paxos variants, and practical implementation details. Conclude with an evaluation of the system's performance using the TPC-C benchmark.
