RocksDB Storage Engine Module for MongoDB

TL;DR

Execute this series of commands to compile MongoDB with RocksDB storage engine:

# install compression libraries (zlib, bzip2, snappy):
sudo apt-get install zlib1g-dev; sudo apt-get install libbz2-dev; sudo apt-get install libsnappy-dev
# get rocksdb
git clone https://github.com/facebook/rocksdb.git
# compile rocksdb
cd rocksdb; USE_RTTI=1 CFLAGS=-fPIC make static_lib; sudo INSTALL_PATH=/usr make install; cd ..
# get mongo
git clone https://github.com/mongodb/mongo.git
# get mongorocks
git clone https://github.com/mongodb-partners/mongo-rocks
# add rocksdb module to mongo
mkdir -p mongo/src/mongo/db/modules/
ln -sf ~/mongo-rocks mongo/src/mongo/db/modules/rocks
# compile mongo
cd mongo; scons

Start mongod using the --storageEngine=rocksdb option.

More information

To use this module, it has to be linked from mongo/src/mongo/db/modules. The build system will automatically recognize it. In the mongo repository directory do the following:

mkdir -p src/mongo/db/modules/
ln -sf ~/mongo-rocks src/mongo/db/modules/rocks

To build you will need to first install the RocksDB library, see INSTALL.md at https://github.com/facebook/rocksdb for more information. If you install in non-standard locations, you may need to set CPPPATH and LIBPATH environment variables:

CPPPATH=/myrocksdb/include LIBPATH=/myrocksdb/lib scons
