vitess VS noms

With Vitess likely merging a lot of its binaries into a single unified binary: https://github.com/vitessio/vitess/issues/7471#issuecomment-...

... it would be a wild future if Vitess replaced the underlying MySQL engine with this as long as the performance is good enough.

Thank you for the compliment!

We recently started adding support for CTEs in Vitess! You can check out https://github.com/vitessio/vitess/pull/14321 if you want to see some technical details of the implementation.

For now, we have added preliminary support by converting them to derived tables internally, but we believe that we need to make CTEs first-class citizens themselves of query planning. Once we make that change, we can look towards supporting recursive CTEs.

This however will take some time, but then, all good things do!

Why would it be a Google project? https://github.com/vitessio/vitess

This is great news. I strolled around https://github.com/vitessio/vitess/issues/12967.

Are there any public discussions of more trade-offs vitess has to make to enable fks?

MySQL + Vitess I noticed Slack gets by using MySQL because they're using Vites. From Slack's post (https://slack.engineering/scaling-datastores-at-slack-with-vitess/) it seems like they choose Vites because it facilitated a smooth transition because it's built on top of MySQL.

This sounds very similar to the connection pooling done by vitess https://vitess.io/.

A lot of this is possible thanks to the magic of Vitess.

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 It is based on Noms [1], which is no longer maintained (they forked it).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 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.

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.

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.

Noms might be what you’re looking for (https://github.com/attic-labs/noms). Dolt is actually a fork of Noms.

People that are interested in a similar feature set should check out https://github.com/attic-labs/noms and the SQL fork of Noms, https://github.com/dolthub/dolt
