Building YDB from sources

From this repository you can build YDB Server and YDB CLI (Command Line Interface utility) executables. You can build using either Yatool or CMake:

• Yatool is the primary multilanguage build/test system being used to build and test YDB. You need to use Yatool and follow the YDB development process to make contributions to the YDB project.
• CMake is a secondary build system available, with CMakelists.txt automatically pregenerated by Yatool. You can build any binary artifact of YDB using CMake.

Create the work directory.

:warning: Please make sure you have at least 80Gb of free space. We also recommend placing this directory on SSD to reduce build times.

mkdir ~/ydbwork && cd ~/ydbwork

Clone the ydb repository

git clone https://github.com/ydb-platform/ydb.git

Change the current working directory to the cloned repository root to perform further commands:

cd ydb

Checkout a branch for build

There are two branches for the latest development update in the YDB repository:

• main - the primary development branch for Yatool build
• cmakebuild - the follower branch for CMake build, synced from main every hour, with generated CMakelists.txt files

Build from the development mainline branches may sometimes be broken for short periods of time, and also some tests may fail. So, you may prefer to build the latest stable versions of YDB Server and CLI. As stable versions of the YDB Server and CLI belong to different commits, it is not possible to get both server and CLI stable executables with a single checkout/build. Checkout and build server first, then CLI, or vice versa.

Stable versions can be built by both Yatool and CMake.

Checkout the latest development update for Yatool build

By default, the main branch is checked out, so you can run Yatool build without executing a checkout command.

Checkout the latest development update for CMake build

To checkout the latest development update for CMake build, run the following command:

git checkout cmakebuild

Check out the latest stable YDB Server version

To build the latest stable version of a YDB Server, check out the latest stable Server tag from the repository. To do so, visit the https://github.com/ydb-platform/ydb/releases/latest page and use the provided 'tag' value in the git checkout <tag> command.

For example, at the time of writing the latest stable release was YDB Server 23.2.12 with a tag 23.2.12, so the checkout command looks like this:

git checkout 23.2.12

Check out the latest stable YDB CLI version

To build a latest stable version of a YDB CLI, check out the latest stable CLI tag from the repository. To do so, visit the https://github.com/ydb-platform/ydb/releases page, scroll down to the top-most 'YDB CLI' release, and use the provided 'tag' value in the git checkout <tag> command.

For example, at the time of writing the latest YDB CLI release was YDB CLI 2.5.0 with a tag CLI_2.5.0, so the checkout command looks like this:

git checkout CLI_2.5.0

Build using Yatool

You can use the native Yatool build for x86_64 under Ubuntu Linux 18+.

Run ya make from the repository root, followed by an optional relative path to the build target. By default, ya make compiles a debug configuration, while you can choose to have release or relwithdebinfo. The latter is recommended for faster builds, as is leverages the YDB remote build cache.

To build a binary, Yatool downloads and caches relevant toolchains from the YDB S3 storage, so you do not need to install anything on the build machine.

To build YDB server run:

./ya make ydb/apps/ydbd --build relwithdebinfo

To build YDB CLI run:

./ya make ydb/apps/ydb --build relwithdebinfo

Upon completion, you will have the ydbd/ydb executables in the ydb/apps/ydbd/ydb/apps/ydb directories, respectively.

You can read more about Yatool options in the YDB documentation.

Build using CMake

You can use CMake build for various arcitectures and operating systems.

YDB server can be built for Ubuntu 18.04, 20.04 and 22.04. Other Linux distributions are likely to work, but additional effort may be required.

YDB CLI can be built for Ubuntu 18+, Windows, and MacOS. Instructions below are provided for Ubuntu only, other options are to be described later.

For Ubuntu versions earlier than 22.04

It is recommended to build YDB on Ubuntu 22.04. Follow these additional instructions if you don't have access to it and need to use an earlier version.

For Ubuntu 18.04, install Python 3.8, create and activate a new virtual environment, and install the latest PIP.

```bash apt-get install python3.8 python3.8-venv python3-venv python3.8 -m venv ~/ydbwork/ve source ~/ydbwork/ve/bin/activate pip install -U pip ```

For Ubuntu 18.04 and Ubuntu 20.04, add CMake and LLVM APT repositories.

```bash wget -O - https://apt.kitware.com/keys/kitware-archive-latest.asc | sudo apt-key add - echo "deb http://apt.kitware.com/ubuntu/ $(lsb_release -cs) main" | sudo tee /etc/apt/sources.list.d/kitware.list >/dev/null wget -O - https://apt.llvm.org/llvm-snapshot.gpg.key | sudo apt-key add - echo "deb http://apt.llvm.org/$(lsb_release -cs)/ llvm-toolchain-$(lsb_release -cs)-14 main" | sudo tee /etc/apt/sources.list.d/llvm.list >/dev/null sudo apt-get update ```

Install dependencies

sudo apt-get -y install git cmake python3-pip ninja-build antlr3 m4 clang-14 lld-14 libidn11-dev libaio1 libaio-dev llvm-14
sudo pip3 install conan==1.59 grpcio-tools==1.57.0

Create the build directory.

cd ~/ydbwork
mkdir build

Install ccache

1. Install ccache into /usr/local/bin/. The recommended version is 4.8.1 or above, the minimum required version is 4.7.

   (V=4.8.1; curl -L https://github.com/ccache/ccache/releases/download/v${V}/ccache-${V}-linux-x86_64.tar.xz | \
    sudo tar -xJ -C /usr/local/bin/ --strip-components=1 --no-same-owner ccache-${V}-linux-x86_64/ccache)
   

2. To speed up the first build time, you may configure ccache to use remote storage of YDB build artifacts:

   ccache -o remote_storage="http://cachesrv.ydb.tech:8080|read-only|layout=bazel"
   ccache -o sloppiness=locale 
   ccache -o base_dir=~/ydbwork/
   

   If you use a non-default work directory, adjust the base_dir ccache option to match it.

Configure

1. Change Conan's home folder to the build folder for better remote cache hit

   export CONAN_USER_HOME=~/ydbwork/build
   

2. Generate build configuration using ccache

   cd build
   cmake -G Ninja -DCMAKE_BUILD_TYPE=Release \
   -DCCACHE_PATH=/usr/local/bin/ccache \
   -DCMAKE_TOOLCHAIN_FILE=../ydb/clang.toolchain \
   ../ydb
