question about rust #4225

I know that the Firebolt project is also developed in Clickhouse, but they are still written in C++, which saves a lot of coding time. Why doesn't databend do this and rewrite it with trust？ |

Good question. On the fact that all current data warehouses code-base suffer from this problem, they are not designed for cloud architectures and are difficult to maintain and grow sustainably. So, we writing one from scratch in Rust:
Current amount of code is about 131293 lines(From tokei). |

This is a good solution so far, but the complexity and maintenance costs are still quite high :) |

Hmm, before I join databend, i am a C\C++ programmer for more than 10 years, after 2 month writing rust code, i am in love with this language.In my opition, Rust fix the core problem in C\C++: the runtime memory bug, such as wild pointer access,memory leaks,buffer overflow, etc. I have write an article about the experience of rust(in Chinese): 周刊（第7期）：一个C系程序员的Rust初体验 - codedump的网络日志 |

Good question.
We evaluated doing Storage and Compute Disaggregated on ClickHouse and found it's hard(There is a post about it).
