FYI, Zero uses incremental view maintenance internally as the core of its sync engine: https://zero.rocicorp.dev/docs/introduction IVM is what allows the core feature of our DX: that users can just do a fairly large qu

I think this is a fascinating and deep question, that I ponder often. I don't feel like I know all the answers, but as the creator of Replicache and Zero here is why I feel a pull to the web and not mobile: - All the normal reasons the

> Using Zero is another option, it has many similarities to Electric, while also directly supporting mutations. The core differentiator of Zero is actually query-driven sync. We apparently need to make this more clear. You build your app

I am confused by this question. Both noms and dolt, and presumably most other prolly tree implementations do what you propose. if they didn't, inserts would be terribly slow.

I was aware of this kind of structure when I coined 'prolly tree'. It's the same thing bup was doing, which I referenced in our design docs: https://github.com/attic-labs/noms/blob/master/d

Hey HN, I just presented this at React Miami and thought you might be interested. I built an app with three upcoming sync engines, and they run side-by-side and interoperate. Happy to answer any questions.

When you say “rebase” what do you mean exactly? Is it the application replaying the transaction including the interactive code, or is it the database writing the same rows/pages that were written last time?

Yes, this is a central issue in sync. For most applications, sync engines just aren't useful without some solution. Of course you need to validate inputs, support fine-grained permissions, etc., as developers have done with web apps fo

No. When we started the project we used prolly trees initially, but we don't need the content addressing feature for Zero and all the hashing was quite expensive. So now we just use a plain immutable b-tree: https://github.c

No, Convex is a client/server system like zero, electric, instant, powersync. If you want a fully decentralized system, check out jazz. It is the best of these currently IMO.

Zero (zerosync.dev) uses transactional conflict resolution, which is what our prior product Replicache and Reflect both used. It is very similar to what multiplayer games have done for decades. It is described here: https://rocic

Sure happy to give my point of view. Top-level response: I think Instant is very cool and I have a lot of respect for that team and their work. I've tried to be accurate below, but I know the instant folks frequent HN so maybe they can

I hesitate to use the word 'deprecated' because it means different things to different people. We'll continue supporting Replicache but won't add new features to it. Even if you don't think you'll need partial

It's even (often) in company's selfish interest to have regulation so that they aren't forced into a race to the bottom.

You should get in the habit of quoting identifiers in pg anyway as there are so many reserved words.
