Class BloomFilter.Builder (3.21.1)

public static final class BloomFilter.Builder extends GeneratedMessageV3.Builder<BloomFilter.Builder> implements BloomFilterOrBuilder

A bloom filter (https://en.wikipedia.org/wiki/Bloom_filter).

The bloom filter hashes the entries with MD5 and treats the resulting 128-bit hash as 2 distinct 64-bit hash values, interpreted as unsigned integers using 2's complement encoding.

These two hash values, named h1 and h2, are then used to compute the hash_count hash values using the formula, starting at i=0:

 h(i) = h1 + (i * h2)

These resulting values are then taken modulo the number of bits in the bloom filter to get the bits of the bloom filter to test for the given entry.

Protobuf type google.firestore.v1.BloomFilter
