mlightning is a tool designed to quickly load data into MongoDB sharded clusters.

Written in C++, it requires the following to compile:

• C++11 support (gcc 4.8.2)
• mongo-cxx-driver using the legacy branch, -std=c++11 is required.
• boost - program options, system, regex, thread, chrono and filesystem. Boost 1.55 in known to work, earlier versions may work, but this hasn't been tested.
• scons (and therefore python)
• tcmalloc (optional)

This program has been verified to compile on Ubuntu 14.04 with gcc 4.8.2 (standard on ubuntu)

sudo apt-get install gcc

sudo apt-get install libtcmalloc-minimal4
cd /usr/lib
sudo ln -s libtcmalloc.so.4 libtcmalloc.so

sudo apt-get install scons duplicity

sudo apt-get install libboost-all-dev

To compile and install the mongo C++ driver (assuming installing into /usr/local is desired):

git clone https://github.com/mongodb/mongo-cxx-driver.git
cd mongo-cxx-driver
sudo scons -j16 --opt=on --c++11 --prefix=/usr/local install

scons

To compile mlightning with tcmalloc:

scons --allocator=tcmalloc

mlightning -h
