Faster – Fast key-value store from Microsoft Research
"What differentiates FASTER are its cache-optimized index that achieves very high performance — up to 160 million operations per second when data fits in memory;"I really dislike when papers make performance claims like this in the introduction. That "160 million" number is so meaningless at face value because everything from the runtime environment to the hardware is going to play a huge role in ops. I rather see how it compares against other key-value stores across a number of configurations and use cases.
