Answer / Manish Kumar Verma
Bloom filters are used in HBase to optimize row-level lookups. They provide a probabilistic data structure that can quickly determine whether an element (in this case, a row key) might be present in a larger set (the table). However, false positives are possible, so if a Bloom filter indicates a row is present, you should always verify the result by fetching the actual data.
