Maysam Yabandeh 67182678a5 Stats for false positive rate of full filtesr ... Summary: Adds two stats to allow us measuring the false positive rate of full filters: - The total count of positives: rocksdb.bloom.filter.full.positive - The total count of true positives: rocksdb.bloom.filter.full.true.positive Not the term "full" in the stat name to indicate that they are meaningful in full filters. block-based filters are to be deprecated soon and supporting it is not worth the the additional cost of if-then-else branches. Closes #3680 Tested by: $ ./db_bench -benchmarks=fillrandom -db /dev/shm/rocksdb-tmpdb --num=1000000 -bloom_bits=10 $ ./db_bench -benchmarks="readwhilewriting" -db /dev/shm/rocksdb-tmpdb --statistics -bloom_bits=10 --duration=60 --num=2000000 --use_existing_db 2>&1 > /tmp/full.log $ grep filter.full /tmp/full.log rocksdb.bloom.filter.full.positive COUNT : 3628593 rocksdb.bloom.filter.full.true.positive COUNT : 3536026 which gives the false positive rate of 2.5% Closes https://github.com/facebook/rocksdb/pull/3681 Differential Revision: D7517570 Pulled By: maysamyabandeh fbshipit-source-id: 630ab1a473afdce404916d297035b6318de4c052		7 years ago
