Hi! Recently I applied Profile-Guided Optimization on RocksDB ang got interesting results on the `db_bench` (a benchmarking tool from RocksDB): Release: ``` DB path: [/tmp/rocksdbtest-1000/dbbench] readrandom : 8.306 micros/op 120392...
close FinishedSingleOp printf to track error in db benchmark easier.
Hi, I know there's this implementation of the iterator available in the documentation: ```cpp leveldb::Iterator* it { getNewIterator() }; std::string const primaryKey { std::string(bestBlockKey.constData(), bestBlockKey.length()) }; // Get the key...
