Real world Rust Why and how we use Rust in TiKV 黄东旭 PingCAP 关于我 ● 黄东旭 Dongxu_Huang ● Open source hacker / Infrastructure Engineer ● MSRA / Netease / Wandoujia / PingCAP ● CTO of PingCAP ● Codis system programming language ○ Maintain by Mozilla ● Stable: 1.13 ○ Stable enough for production use ● Alternative to C/C++ Why Rust? ● Safe ○ Thread safety guarantee ○ Segfaults free ● Blazingly fn main() { let a = vec![1,2,3]; do_vec(a); println!("{}", a) } 内存安全 error[E0382]: use of moved value: `a` --> src/main.rs:6:20 | 5 | do_vec(a); | - value moved here

Python? ● Writing extensive APIs in Python - low boilerplate ● Familiar for domain experts ● Easy to use ○ Amazing interactive support out of the box (IPython) ○ Jupyter notebooks provide a great research Cython 476ns 119ns 57ns 54ns 61K *: C++ program contains the std::chrono library to time, others use python to do that Everything compiled with clang++12 -fPIC -O3Some perf numbers: per increment runtime boost::python::object ○ boost::python::object is a smart pointer around a PyObject* ○ Only useful to use bpy::object if you’re going to keep it around ○ Why would we want to do this?Arguments to functions
