There are 3 parameters to configure the bloom filter:
fpp
: False positive probability of the bloom filter (from 0
to 1

by default). The lower the fpp
, the higher accuracy the bloom filter has, but it will also increase the size of the bloom filter.
maxSizeInBytes
: Maximum size of the bloom filter (unlimited by default). If a fpp

loadOnHeap
: Whether to load the bloom filter using heap memory or off-heap memory (false
by default).
