How Dolt Stores Table Data
This is from 2022. It is based on Noms [1], which is no longer maintained (they forked it).
I think the Noms doc linked from this article [2] is clearer than the article itself. That said I sill cannot turn my head around to grasp how this entire thing work tbh. I hope they wrote a peer reviewed paper to serve the audience better.

I was wrong. CRDTs are the future
I am. But i know very little about CRDTs lol, so we'll see how that goes. I'm interested in converting some immutable, local-first data warehouse tooling i enjoy to a CRDT version. Prior it was more.. Git-like. Basically just Git with data structures inspired-massively from Noms[1].
The thing i've found most interesting is it appears[2] that CRDT backends need to expose CRDT flavored types to users. Which is to say how i'm writing this combines the notion of a type, say `[i32]` with how you want the merges to work. CRDT works great but based on my amateur-hour researching on the subject i don't feel you can write a single CRDT merge strategy for a single data type ala `[i32]` and have it be always correct. Applications need to indicate enough context on what makes sense for a given data type.
So yea, i agree with you. I'm interested in making a database-like thing, backed by CRDTs, but i also have seen very few general purpose implementations with CRDTs. It feels like i'm breaking "new ground", while having no idea what i'm doing and having no intention of being an actual researcher here. I'm just making apps i enjoy heh.

Picking low-hanging memory usage bugs of an open source database
Most of the changes are in the noms package which used to live in a separate repo (https://github.com/attic-labs/noms), but Dolt has since adopted them.

Downsides of Offline First
Not much more to say other than Noms was my favorite project (https://github.com/attic-labs/noms) for a while until acquisition and the engineers are now the ones behind Replicache (https://replicache.dev/).
I think this is going to be the next "Realm" that works everywhere.
