blockedFprAt
blockedFprAt(
bitsPerKey):number
Defined in: packages/distillate/src/blocked/blocked.ts:55
Modeled false-positive rate of a split-block filter at bitsPerKey. A block
holding j keys has FPR (1 - (1 - 1/32)^j)^8 (8 lanes of 32 bits, one probe
each); the filter’s rate averages that over the Poisson block load
lambda = 256 / bitsPerKey. This clustering average is why the blocked curve
is not linear in log10(1/epsilon).
