This project (rocksdb.replicated) is to demonstrate how to use the replication framework provided in Robust Distributed System Nucleus (rDSN) to quickly turn a local component into a partitioned and replicated service for scalability and reliability. RocksDB is an open source local storage engine from Facebook originated from levelDB by Google. See details below.

-- STATUS UPDATE: functional features done, performance test and turning ahead ---

Installation

• Install rDSN
• git clone rocksdb.replicated
• Run the following commands and it should work

cd $rockdb$/replication/src
mkdir build
cd build
cmake ..
make
cd bin/rrdb
./rrdb config.ini

• For more information like bug support and how to deploy etc., please go to rDSN for details.

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.
