Summary: Results from 2015 compiler. This improve sequential insert. Random Read results are inconclusive but I hope 2017 will do a better job at inlining. Before: fillseq : **3.638 micros/op 274866 ops/sec; 213.9 MB/s** After: fillseq : **3.379 micros/op 295979 ops/sec; 230.3 MB/s** Closes https://github.com/facebook/rocksdb/pull/3645 Differential Revision: D7382711 Pulled By: siying fbshipit-source-id: 092a07ffe8a6e598d1226ceff0f11b35e6c5c8e4
RocksDB: A Persistent Key-Value Store for Flash and RAM Storage
RocksDB is developed and maintained by Facebook Database Engineering Team. It is built on earlier work on LevelDB by Sanjay Ghemawat (sanjay@google.com) and Jeff Dean (jeff@google.com)
This code is a library that forms the core building block for a fast key value server, especially suited for storing data on flash drives. It has a Log-Structured-Merge-Database (LSM) design with flexible tradeoffs between Write-Amplification-Factor (WAF), Read-Amplification-Factor (RAF) and Space-Amplification-Factor (SAF). It has multi-threaded compactions, making it specially suitable for storing multiple terabytes of data in a single database.
