We migrated to SQL. Our biggest learning? Don't use Prisma
This is a very strange comment section. And this article is insanely poorly written.
> Last week, we completed a migration that switched our underlying database from MongoDB to Postgres.
Okay cool, but why? MongoDB is a very capable and fast database.
> It was a shock finding out that Prisma needs almost a ādbā engine layer of its own. Read more about it here: https://www.prisma.io/docs/concepts/components/prisma-engine...
If you did any research on Prisma rather than diving in head-first, you'd realize this is a core part of why Prisma exists.
> we discovered that at a low level, Prisma was fetching data from both tables and then combining the result in its āRustā engine. This was a path for an absolute trash performance.
Can you confirm this is actually the case? Can you show some benchmarks re: this claim? Or are you just assuming this is the case?

Prisma laying off 28% staff
If you wish to auto-generate migrations, there are declarative schema change tools available for most relational databases. I'm the creator of Skeema [1] which provides them for MySQL, but there are options for other DBs too [2][3][4].
Prisma's migration system actually partially copied Skeema's design, while giving credit in a rather odd fashion which really rubbed me the wrong way: "The workflow of working with temporary databases and introspecting it to determine differences between schemas seems to be pretty common, this is for example what skeema does." [5]
While I doubt I was the first person to ever use that technique, I absolutely didn't copy it from anywhere, and it was never "pretty common". I'm not aware of any other older schema change systems that work this way.

Maintenance of popular ORMs (explanation inside)
If you're serious about your review then you shouldn't ignore the fact that Prisma has a big blob of Rust code at its core, where other ORMs use standard database adapters from NPM. As someone who has maintained database adapters for other languages, let me tell you that the maintenance burden of that is quite significant. Especially if they ever want to support more advanced database features. If the company behind Prisma ever runs out of money, the project is probably toast.

If Prisma's query engine is compiled by Rust, why don't I need Rust to compile it?
prisma generate generates the code for the Prisma client. The code generated for the client is all JavaScript which calls into the āPrisma Engineā Rust native Node module to perform database operations. As others here have said, the Prisma Engine is pre-compiled by rustc via CI and gets dowloaded to your machine as a pre-built binary by npm, so thereās no need for you to build it yourself by running the Rust compiler locally.

I went about learning Rust
We solved this with flat vectors and just sharing index values in cheap walker objects. It is much nicer to work with compared to arc/weak pointers.

MariaDB to go public at $672M valuation
Thanks! I know of a couple Postgres tools that work in a declarative fashion: migra [1] and sqldef [2].
Migra is Postgres-specific. Its model is similar to Skeema's, in that the desired-state CREATEs are run in a temporary location and then introspected, to build an in-memory understanding of the desired state which can be diff'ed against the current actual state. (This approach was also borrowed by Prisma Migrate [3]). In this manner, the tool doesn't need a SQL parser, instead relying on the real DBMS to guarantee the CREATE is interpreted correctly with your exact DBMS version/flavor/settings.
In contrast, sqldef supports multiple databases, including Postgres and MySQL (among others). Unlike other tools, it uses a SQL parser-based approach to build its in-memory understanding of the desired state. As a DB professional, personally this approach scares me a bit, given the amount of nonstandard stuff in each DBMS's SQL dialect. But I'm inherently biased on this topic. And I will note sqldef's author is a core Ruby committer and JIT author, and is extremely skilled at parsers.

Ollama is now available on Windows in preview
But these are typically filling the usecases of productivity applications, not āenginesā.
Microsoft Word doesnāt run its grammar checker as an external service and shunt JSON over a localhost socket to get spelling and style suggestions.
Photoshop doesnāt install a background service to host filters.
The closest pattern I can think of is the ālanguage serversā model used by IDEs to handle autosuggest - see https://microsoft.github.io/language-server-protocol/ - but the point of that is to enable many to many interop - multiple languages supporting multiple IDEs. Is that the expected usecase for local language assistants and image generators?

A guide on Neovim's LSP client
A language server is an external program that follows the Language Server Protocol. The LSP specification defines what type of messages a language server can receive, and also how it should respond. The idea here is that any tool that follows the LSP specification can communicate with a language server.

> There's a strange dance of IDEs coming and going, with their idiosyncracies and partial plugins.
The Language Server Protocol [1] is the best thing to happen to text editors. Any editor that speaks it gets IDE features. Now if only they'd adopt the Debug Adapter Protocol [2]...

The More You Gno: Gno.land Monthly Updates - 6
The Gno Language Server (gnols) is an implementation of the Language Server Protocol (LSP) for the Gno programming language. It is similar to the equivalent āgoplsā project for Go, as they can be plugged into your code editor through extensions and allow you to access handy features, such as autocompletion, formatting, and compile-time warnings/errors. Gnols makes writing code simpler, working with several editors to suit your preferences. To try it out, visit the CONTRIBUTING.md file, which contains instructions to get you started. Our current documentation targets Vim, Neovim, and SublimeText, but can likely be used with any editor that supports LSP. Feel free to contribute to improving Gnols and adding more features. Itās well-written, and simple to dive into the code and add more capabilities.

LSP could have been better

Show HN: Postgres Language Server
hey HN. this is a Language Server[0] designed specifically for Postgres. A language server adds features to IDEs (VSCode, NeoVim, etc) - features like auto-complete, go-to-definition, or documentation on hover, etc.
there have been previous some attempts at adding Postgres support to code editors. usually these attempts implement a generic SQL parser and then offer various "flavours" of SQL.
This attempt is different because it uses the actual Postgres parser to do the heavy-lifting. This is done via libg_query, an excellent C library for accessing the PostgreSQL parser outside of the server. We feel this is a better approach because it gives developers 100% confidence in the parser, and it allows us to keep up with the rapid development of Postgres.
this is still in early development, and mostly useful for testers/collaborators. the majority of work is still ahead, but we've verified that the approach works. we're making it public now so that we can develop it in the open with input from the community.
a lot of the credit belongs to pganalyze[1] for their work on libg_query, and to psteinroe (https://github.com/psteinroe) who the creator and maintainer of the LSP.

How to configure vim like an IDE
LSP stands for "Language Server Protocol", which defines how a language server and an editor (client) can communicate to provide code navigation, completion, etc. (source). Traditional IDE's would have something similar to this baked-in already, but proprietary to their software/language; whereas LSP is an open standard, so anything could implement it.
