# SGLang Router (Experimental)
|
|
|
|
SGLang router is a standalone module implemented in Rust to achieve data parallelism across SGLang instances.
|
|
|
|
## Prerequisites
|
|
|
|
- Rust and Cargo installed
|
|
|
|
```bash
|
|
# Install rustup (Rust installer and version manager)
|
|
curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh
|
|
|
|
# Follow the installation prompts, then reload your shell
|
|
source $HOME/.cargo/env
|
|
|
|
# Verify installation
|
|
rustc --version
|
|
cargo --version
|
|
```
|
|
|
|
- Python with pip installed
|
|
|
|
|
|
## Build Process
|
|
|
|
### 1. Build Rust Project
|
|
|
|
```bash
|
|
cargo build
|
|
```
|
|
|
|
### 2. Build Python Binding
|
|
|
|
#### Option A: Build and Install Wheel
|
|
1. Build the wheel package:
|
|
```bash
|
|
pip install setuptools-rust wheel build
|
|
python -m build
|
|
```
|
|
|
|
2. Install the generated wheel:
|
|
```bash
|
|
pip install <path-to-wheel>
|
|
```
|
|
|
|
#### Option B: Development Mode
|
|
|
|
For development purposes, you can install the package in editable mode:
|
|
```bash
|
|
pip install -e .
|
|
```
|
|
|
|
**Note:** When modifying Rust code, you must rebuild the wheel for changes to take effect.
|
|
|
|
## CI/CD Setup
|
|
|
|
The continuous integration pipeline consists of three main steps:
|
|
|
|
### 1. Build Wheels
|
|
- Uses `cibuildwheel` to create manylinux x86_64 packages
|
|
- Compatible with major Linux distributions (Ubuntu, CentOS, etc.)
|
|
- Additional configurations can be added to support other OS/architectures
|
|
- Reference: [cibuildwheel documentation](https://cibuildwheel.pypa.io/en/stable/)
|
|
|
|
### 2. Build Source Distribution
|
|
- Creates a source distribution containing the raw, unbuilt code
|
|
- Enables `pip` to build the package from source when prebuilt wheels are unavailable
|
|
|
|
### 3. Publish to PyPI
|
|
- Uploads both wheels and source distribution to PyPI
|
|
|
|
The CI configuration is based on the [tiktoken workflow](https://github.com/openai/tiktoken/blob/63527649963def8c759b0f91f2eb69a40934e468/.github/workflows/build_wheels.yml#L1).
