RAMCloud, CURP improved write latency by ˘2x (14 s!7.1 s) and write throughput by 4x. Given that the entire dataset fits into main memory, these running times are not acceptable.

CockroachDB is architected to handle unpredictability and survive machine, datacenter, and region failures. The RAMCloud idea, while innovative, is similar to one posed by a company called RNA Networks, which was recently bought by Dell, Duplessie says. Compared to un-replicated RAMCloud, CURP’s latency overhead for 3-way replication is just 1 s (6.1 s vs 7.1 s).
