We present SkimpyStash, a RAM space skimpy key-value store on flash, designed for high throughput server applications. The distinguishing feature of SkimpyStash is the design goal of extremely low RAM footprint at about 1 (+/- 0.5) byte per key-value pair, which is more aggressive than earlier designs. By being RAM space frugal, SkimpyStash can accommodate larger flash drive capacities for storing
