tldr: FaRM
Part of the tldr series , which summarizes papers I'm currently reading. Inspired by the morning paper . Optimistic Concurrency Control + FaRM [2015] Dragojević et al. Introduction Before FaRM, distributed transactions were thought of as convenient for programmers, but slow. However, FaRM guarantees 90-100 million transactions/second on 90 machines! Those transactions are replicated 3 times (by default) and persistent. What is FaRM and how did it accomplish this? Systems often have to make tradeoffs between availability, consistency, performance, and simplicity. However, FaRM is a main memory platform for data centers that doesn't compromise on any of these because it minimizes network, storage, and CPU bottlenecks by: Assuming the whole dataset can fit in RAM, so no disk I/O Using non-volatile RAM, so no disk I/O Using a one-sided RDMA for a fast network Bypassing the OS kernel for fast network access Designing transaction and replication protocol...
