An XOR filter is designed as a drop-in replacement for a Bloom filter in the case where all the items to store in the filter are known in advance. Like the Bloom filter, it represents an approximation of a set where false negatives are not allowed, but false positives are. Like a Bloom filter, an XOR filter stores a large array of bits. can you go offshore in bassmaster 22 https://bohemebotanicals.com
