Mayank Agarwal 2a986919d6 Make rocksdb-deletes faster using bloom filter ... Summary: Wrote a new function in db_impl.c-CheckKeyMayExist that calls Get but with a new parameter turned on which makes Get return false only if bloom filters can guarantee that key is not in database. Delete calls this function and if the option- deletes_use_filter is turned on and CheckKeyMayExist returns false, the delete will be dropped saving: 1. Put of delete type 2. Space in the db,and 3. Compaction time Test Plan: make all check; will run db_stress and db_bench and enhance unit-test once the basic design gets approved Reviewers: dhruba, haobo, vamsi Reviewed By: haobo CC: leveldb Differential Revision: https://reviews.facebook.net/D11607		12 years ago
