It is expensive in several dimensions to build a narrowly tailored database engine from scratch. Database engines are not modular, you can't assemble them from arbitrary parts while maintaining control of their basic characteristics.

Aren't things like LMDB and RocksDB sort of modular parts you can build databases around?

We dive into this in detail here in “Let's Remix Distributed Database Design!”, a talk given at the Recurse center: https://www.youtube.com/watch?v=rNmZZLant9o

TLDR: Here's also a 10 min lightning version given at HYTRADBOI '22, on why technology/research has changed enough that we need new storage engines to take advantage of where things are going: https://www.youtube.com/watch?v=yBBpUMR8dHw

That 2nd video is awful, it's just a talking head with the content repeated as text. It's the worst of both video and text.

???

Don't mind this guy and just watch the video. It's pretty much the same format that is used for conference videos everywhere.

It's fine.

The 2nd vid I downloaded. 18.5 meg. A transcription would be maybe 2K? And I could read it at my own speed instead of having to skip back when it covered things too fast, and there could be URLs to useful stuff like papers and wiki pages (like, perhaps, to Eytzinger Binary Search which I'd never heard of).

The video added precisely nothing to a text transcript and wasted an incredible factor for bandwidth. Just.. why?

Humans like me (and a couple other billion on YouTube) enjoy watching another human explaining stuff to them.

If plain text is your thing then that's good as well, to each its own.

I'm curious, did you already know what a Eytzinger Binary Search was?

No.
