[Media] Finally finished building a relational database from scratch.

Hey everyone,

I'm a 4th year CS undergrad, I've been learning about databases since the last year as I eventually wanted to build one. After giving the build several attempts by sometimes building just the storage engine, or the front-end, etc., I finally did complete the build last week. I felt like its ready to share, so I'm making this post here.

Repo: https://github.com/pixelooz/hinder-db

Its called HinderDb. It's a cli only (for now) database with a custom slotted page B+Tree storage engine, buffer pool, secondary indexes, wal, volcano style execution pipeline, etc.

I wrote it in rust as I like writing rust and this would be another way to get better at it, plus the domain just seemed like a good fit.

It was mostly a learning project for me, but ended up better than I had orginally planned for, so I'm quite happy with that. I originally got interested in databases and stuff through Designing Data Intensive Applications book, and since then always wanted to build one. I had already given the storage engine a couple of tries, by reading some already existing material (Writing your own database type of books) and codebases, but this was the first time writing it complete, and its works quite nice.

I am keeping this as my main portfolio project as well since I'll be applying for jobs/intenships. So, if any working professionals can offer any feedback - something I should improve, any apparent flaws, or the next thing I should look into. I'll really appreciate it.

P.S: I have solid knowledge in backend as well and I'll be applying for on-site (in India) as well as global remote positions, so if you can offer any advice regarding navigating the job market rn, it'd be much appreciated.
