TokuFT is a high-performance, transactional key-value store, used in the TokuDB storage engine for MySQL and MariaDB and in TokuMX, the high-performance MongoDB distribution.

TokuFT is provided as a shared library with an interface similar to Berkeley DB.

To build the full MySQL product, see the instructions for Tokutek/ft-engine. To build TokuMX, see the instructions for Tokutek/mongo. This document covers TokuFT only.

TokuFT is built using CMake >= 2.8.9. Out-of-source builds are recommended. You need a C++11 compiler, though only GCC >= 4.7 and Apple's Clang are tested. You also need zlib development packages (yum install zlib-devel or apt-get install zlib1g-dev).

You will also need the source code for jemalloc, checked out in third_party/.

git clone git://github.com/Tokutek/ft-index.git ft-index
cd ft-index
git clone git://github.com/Tokutek/jemalloc.git third_party/jemalloc
mkdir build
cd build
CC=gcc47 CXX=g++47 cmake \
    -D CMAKE_BUILD_TYPE=Debug \
    -D BUILD_TESTING=OFF \
    -D USE_VALGRIND=OFF \
    -D CMAKE_INSTALL_PREFIX=../prefix/ \
    ..
cmake --build . --target install

This will build libtokudb.so and libtokuportability.so and install it, some header files, and some examples to ft-index/prefix/. It will also build jemalloc and install it alongside these libraries, you should link to that if you are planning to run benchmarks or in production.

TokuFT is supported on 64-bit Centos, should work on other 64-bit linux distributions, and may work on OSX 10.8 and FreeBSD. TokuFT is not supported on 32-bit systems.

Transparent hugepages is a feature in newer linux kernel versions that causes problems for the memory usage tracking calculations in TokuFT and can lead to memory overcommit. If you have this feature enabled, TokuFT will not start, and you should turn it off. If you want to run with transparent hugepages on, you can set an environment variable TOKU_HUGE_PAGES_OK=1, but only do this for testing, and only with a small cache size.

TokuFT uses CTest for testing. The CDash testing dashboard is not currently public, but you can run the tests without submitting them.

There are some large data files not stored in the git repository, that will be made available soon. For now, the tests that use these files will not run.

In the build directory from above:

cmake -D BUILD_TESTING=ON ..
ctest -D ExperimentalStart \
      -D ExperimentalConfigure \
      -D ExperimentalBuild \
      -D ExperimentalTest

Please report bugs in TokuFT to the issue tracker.

We have two publicly accessible mailing lists for TokuDB:

• tokudb-user@googlegroups.com is for general and support related questions about the use of TokuDB.
• tokudb-dev@googlegroups.com is for discussion of the development of TokuDB.

and two for TokuMX:

• tokumx-user@googlegroups.com is for general and support related questions about the use of TokuMX.
• tokumx-dev@googlegroups.com is for discussion of the development of TokuMX.

We are also available on IRC on freenode.net, in the #tokutek channel.

TokuFT is available under the GPL version 2, with slight modifications. See README-TOKUDB.
