Zhongyi Xie 408205a36b use user_key and iterate_upper_bound to determine compatibility of bloom filters (#3899) ... Summary: Previously in https://github.com/facebook/rocksdb/pull/3601 bloom filter will only be checked if `prefix_extractor` in the mutable_cf_options matches the one found in the SST file. This PR relaxes the requirement by checking if all keys in the range [user_key, iterate_upper_bound) all share the same prefix after transforming using the BF in the SST file. If so, the bloom filter is considered compatible and will continue to be looked at. Closes https://github.com/facebook/rocksdb/pull/3899 Differential Revision: D8157459 Pulled By: miasantreble fbshipit-source-id: 18d17cba56a1005162f8d5db7a27aba277089c41		2018-06-26 15:57:26 -07:00
