RobinHood: tail latency aware caching – dynamic reallocation from cache-rich to cache-poor
"Robin Hood doesn’t necessarily allocate caching resources to the most popular back-ends, instead, it allocates caching resources to the backends (currently) responsible for the highest tail latency. ... RobinHood operates in 5 second time windows, repeatedly taxing every backend by reclaiming 1% of its cache space and redistributing the wealth to cache-poor backends. ... At the end of the window RobinHood calculates the request blocking count (RBC) of each backend – the number of times it was responsible for the slowest query."
