This commit adds two new targets to the Makefile: rocksdb.cc and rocksdb.h These files, when combined with the c.h header, are a self-contained RocksDB source distribution called an amalgamation. (The name comes from SQLite's, which is similar in concept.) The main benefit of an amalgamation is that it's very easy to drop into a new project. It also compiles faster compared to compiling individual source files and potentially gives the compiler more opportunity to make optimizations since it can see all functions at once. rocksdb.cc and rocksdb.h are generated by a new script, amalgamate.py. A detailed description of how amalgamate.py works is in a comment at the top of the file. There are also some small changes to existing files to enable the amalgamation: * Use quotes for includes in unity build * Fix an old header inclusion in util/xfunc.cc * Move some includes outside ifdef in util/env_hdfs.cc * Separate out tool sources in Makefile so they won't be included in unity.cc * Unity build now produces a static library Closes #733 |

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.
Design discussions are conducted in https://www.facebook.com/groups/rocksdb.dev/
