Summary: Create a benchmark for testing memtablereps. This diff is a bit rough, but it should do the trick until other bootcampers can clean it up. Addressing comments Removed the mutexes Changed ReadWriteBenchmark to fix number of reads and count the number of writes we can perform in that time. Test Plan: Run it. Below runs pass ./memtablerep_bench --benchmarks fillrandom,readrandom --memtablerep skiplist ./memtablerep_bench --benchmarks fillseq,readseq --memtablerep skiplist ./memtablerep_bench --benchmarks readwrite,seqreadwrite --memtablerep skiplist --num_operations 200 --num_threads 5 ./memtablerep_bench --benchmarks fillrandom,readrandom --memtablerep hashskiplist ./memtablerep_bench --benchmarks fillseq,readseq --memtablerep hashskiplist --num_scans 2 ./memtablerep_bench --benchmarks fillseq,readseq --memtablerep vector Reviewers: jpaton, ikabiljo, sdong Reviewed By: sdong Subscribers: dhruba, ameyag Differential Revision: https://reviews.facebook.net/D22683 |

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.

See the github wiki for more explanation.
The public interface is in include/. Callers should not include or
rely on the details of any other header files in this package. Those
internal APIs may be changed without warning.
