AresDB: Uber’s GPU-Powered Open-Source, Real-Time Analytics Engine
Any good resources on where GPU DBs offer significant wins? Especially, but not only, if it wins in cost efficiency for some workload.My naïve impression working at smaller scales is that in a reasonably balanced system, storage is often the bottleneck, and if it can deliver data fast enough the CPU probably won't break a sweat counting or summing or so on. The amount of interest in GPU databases, though, suggests that's not the case for some interesting workloads.
