## There is now a SQL port of Doom on CedarDB

There is an ongoing joke that if a device can perform calculations and has a display it will be used to run Doom. The same way a programming language is considered successful if Doom has been ported to it. Lukas Vogel, has added one more language to […]

用純 SQL 打造類 DOOM 的多人射擊遊戲 https://cedardb.com/blog/doomql/

這篇文章介紹了一個極具實驗性的專案「DOOMQL」，作者利用資料庫 CedarDB，完全透過 SQL 撰寫與執行，打造出一個可多人連線的類 DOOM 射擊遊戲。靈感來自早前 DuckDB-WASM 的單人版 DOOM，作者希望徹底挑戰「一切都在 SQL 完成」的極限，因此在休假期間投入大量時間開發。他將遊戲狀態完整存放在資料庫中，例如地圖、玩家、輸入指令、血量與彈藥等，並透過 SQL 的 `VIEW` 建立即時的 3D 場景渲染流程，再配合一個簡單 Shell […]

#CedarDB is pretty cool in the way they use pretty lightweight B-trees to move data from "hot" tuples in row-oriented storage to efficient column-oriented data for "cold" data that only gets hit by analytics: cedardb.com/blog/colibri/

Once you think about it, it's a pretty straightforward design!

It's fast, ridiculous, and surprisingly elegant.

Ever wished your analytics could keep up with reality instead of lagging behind?

We wrote about connecting #CockroachDB change data capture (CDC) with #CedarDB, and what that means for running lightning-fast analytical queries on live data.

CedarDB on why they picked C++ over Rust
Rust is a great language. I really enjoy using it. However, when it comes to database systems, I would still choose C++ over Rust. I know this may be unpopular, but during the development of CedarDB, we discussed this and decided to continue using C++. The main reasons were safety and undefined behavior (UB). Shouldn't safety be a reason to choose Rust over C++? In theory, yes. That's what I personally enjoy about Rust: you get much more safety by default than in C++. However, when you absolutely need to use potentially unsafe code, Rust makes things much harder. In a code-generating database system like CedarDB, which uses many low-level CPU features, intrusive data structures, and optimistic, racy memory access with validation, you would definitely need the unsafe keyword. Once you write unsafe code in Rust, all bets are off. It's very easy to run into UB with unsafe code, much easier than with C++. The rules of what constitutes UB are already complex in C++ (I would know, I have
