cube.js
📊 Cube’s universal semantic layer platform is the next evolution of OLAP technology for AI, BI, spreadsheets, and embedded analytics
Project mention: Getting AI to write good SQL: Text-to-SQL techniques explained | news.ycombinator.com | 2025-05-16the short answer: use a semantic layer.
It's the cleanest way to give the right context and the best place to pull a human in the loop.
A human can validate and create all important metrics (e.g. what does "monthly active users" really mean) then an LLM can use that metric definition whenever asked for MAU.
With a semantic layer, you get the added benefit of writing queries in JSON instead of raw SQL. LLM's are much more consistent at writing a small JSON vs. hundreds of lines of SQL.
We[0] use cube[1] for this. It's the best open source semantic layer, but there's a couple closed source options too.

paradedb
ParadeDB is a modern Elasticsearch alternative built on Postgres. Built for real-time, update-heavy workloads.
ParadeDB Search and Analytics. Search pg_search (ParadeDB's rust-based version) Previously named pg_bm25. This is huge and it takes a long long time to compile! Adds a ton of Lucene-like features, based on , a Rust-based Lucene alternative. Still doesn't provide a text-based query parser. Analytics pg_analytics This has been deprecated, due to refocus on pg_search, even for analytics. Part of ParadeDB.

InfluxDB
InfluxDB – Built for High-Performance Time Series Workloads. InfluxDB 3 OSS is now GA. Transform, enrich, and act on time series data directly in the database. Automate critical tasks and eliminate the need to move data externally. Download now.
-
materialize
Real-time Data Integration and Transformation: use SQL to transform, deliver, and act on fast-changing data. (by MaterializeInc)
Did I miss in the article where OP reveals the magic database that actually does this?
3rd party solutions like https://readyset.io/ and https://materialize.com/ exist specifically because databases don’t actually have what we all want materialized views to be.
-
readyset
Readyset is a MySQL and Postgres wire-compatible caching layer that sits in front of existing databases to speed up queries and horizontally scale read throughput. Under the hood, ReadySet caches the results of cached select statements and incrementally updates these results over time as the underlying data changes.

Yeah, they would often claim that C API is at fault, but believe it or not, blaming Rust just as much. I've had an interesting discussion with pgrx people: https://github.com/pgcentralfoundation/pgrx/issues/1897#issu... to quote @workingjubilee
> Rust has formally rejected the notion that any function can return twice. Even LLVM has no special knowledge of the name of "sigsetjmp" or "setjmp", only that some functions can return twice.
> Thus, when you call sigsetjmp or setjmp from Rust, Rust doesn't believe that you called a function that can return twice. The Rust compiler refuses to annotate it with the required LLVMIR annotation. Thus LLVM sees a call to sigsetjmp that it believes cannot return twice... it's just an ordinary function that someone named "sigsetjmp" because they have a sense of humor. What LLVM does next is between itself and whatever gods that compilers believe in, and we have no more voice in such a matter.
In this particular case, it's hardly the fault of a "C wrapper."

i've been working on a database management tui called rainfrog (https://github.com/achristmascarl/rainfrog). it supports postgres, mysql, and sqlite, and we recently added several new features such as:

I use a fork of sqlx in SQLPage [1]. I think my main complaint about it is runtime errors (or worse, values decoded as garbage) when decoding SQL values to the wrong rust type.
