摘要:
Multiple Bloom filters are generated to partition data between first and second disjoint data sets of elements. Each element in the first data set is assigned to a bucket of a first set of buckets, and each element in the second data set is assigned to a bucket of a second set of buckets. A Bloom filter is generated for each bucket of the first set of buckets. The Bloom filter generated for a bucket indicates that each element assigned to that bucket is part of the first data set, and that each element assigned to a corresponding bucket of the second set of buckets is not part of the first data set. Additionally, a Bloom filter corresponding to a subsequently received element can be determined and used to identify whether that subsequently received element is part of the first data set or the second data set.
