Folks, in your launch posts remember to describe what you're launching and what it's for. Ideally in the opening paragraph.
- Intro: Explains problem but not what is Neki or what it's for.
- Why Neki: Explains alternatives and why they suck but not what is Neki or what it's for.
- How does Neki work: Describes the technical components but not what is Neki or what it's for.
- What you get beyond sharding: Explains how to run/deploy but not what is Neki or what it's for.
- What is a platform preview + Try Neki today: 140 words on the definition of "preview" and links to get started... but not what is Neki or what it's for.
Edit: The landing page has 100x more useful information up front -> https://neki.dev/
Edit #2: They've since added a "What is Neki" section. Good reaction time.

Yeah this meta commentary on HN is very confusing for me. The structure of the article is literally
- short paragraph saying "we launched neki"
- short paragraph saying why neki was needed
- paragraphs about what neki is (with a header)
That seems like a very reasonable structure for a blog post like this one. Not being able to get to the third paragraph of a blog post seems like a "you" problem, not a blog problem.

Why "sadly"? The person writing a link should provide enough detail for readers to figure out whether they should follow the link. I rolled my eyes the first time I saw this entry on HN because it just said "Neki" and the (generic) target domain name. A two-word description got added, and that makes it interesting instead.

The top concern I've gotten from dev teams when proposing HA distributed postgres (e.g through RDS Aurora global) is that eventual consistency is not suitable for many workloads.
Does Neki solve for this, and if so how? My understanding of CAP theorem is that this basically requires some compromises around availability, but I'm curious as to what that looks like in practice here.
mcpherrinm 14 hours ago [-]
Assuming it works the same way as their MySQL product, Vitess:
The usual way to run it is that you partition your db based on something like a user, so that single user gets a consistent DB, but anything cross-shard may not be.
I know when I worked at Block, Cashapp was using Vitess and getting cross-shard DB writes down and functioning correctly was one of the major blockers to adoption. (though I just did tls management for vitess and didn't write any workloads on top of it, so my impression might be a bit off)
ronfriedhaber 14 hours ago [-]
Therefore, Consistency guarantees are based on implementing application-specific partitioning (correctly)?
Same here, first thing I need to know when considering a distributed system is how consistency is handled. If it's eventual consistency, what is the replication lag like? If it's strong consistency, can their network handle that? What happens when a node goes down?

The first thing I want to know when looking at a distributed system is how consistency is handled, ctrl+f for "consis" on both the blog post and neki.dev has zero hits. So I can only assume it will have eventual consistency with a considerable replica lag for real-time systems.

We went as far as we could on GCP before PlanetScale. Spanner is amazing but also amazingly expensive. And CloudSQL, also amazing as long as you don’t need write scaling. PlanetScale (Vitess+MySQL plus their branching / deployment and monitoring tools) is just not a combination offered on GCP. And while I didn’t use Aurora, from talking to and exploring AWS it doesn’t really have this combination either.

Curious to compare your implementation to ours [1] some day (if you guys open source it).
Are you one of the developers ? If so, you need to add a specific page explaining in detail the guarantees that this gives.
For example: point 08 says "Assign different tables or workloads to different shard groups" and point 02 says "Split hot shards as workloads grow". How do those interact ? Can a single table be split across multiple shards ? If so don't you need 2pc to enforce primary key constraints ?

Yet. But it’s built by the guy who created Vitess and cofounded PlanetScale, so while it doesn’t have sharding implemented at the moment I think it would be foolish to discount it. Plus it’s open source.
kelp 10 hours ago [-]
The PlanetScale team spent years improving Vitess with lessons learned from many different high scale customer workloads. We continue to invest in and improve Vitess. It's a substantial and growing part of our business.
Vitess today is not the Vitess of 2021. About 70% of the current codebase was written in the last five years, based on lessons we learned running it at scale.
Neki is built for Postgres from the ground up, by the engineers who did that work.
On the Multigres comparison, I'll admit we get a bit salty, mostly because "Vitess for Postgres" invites the comparison. But to date there's no public evidence of a working sharding implementation in Multigres. Their sharding design doc landed this week, and it lists cross-shard query planning and resharding execution as explicitly out of scope.
Neki does sharding today, including online resharding that switches traffic without a maintenance window. It isn't open source, but you can spin up a cluster and try it yourself.
