Barbour, A D; Phatarfod, R (1997). Dimensioning a multiple hashing scheme. Journal of Applied Probability, 34(2):477-486.
The number of items of data which are irretrievable without additional effort after hashing can be greatly reduced if several hash tables are used simultaneously. Here we show that, in a multiple hashing scheme, this number has a distribution very close to Poisson. Thus choosing the number and sizes of the tables to minimize the expected number of irretrievable items is the right way to dimension a scheme.
