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.

pg_mooncake "Postgres-Native Data Warehouse" Provides column stores in PostgreSQL (Iceberg, Delta Lake). Uses DuckDB to query. Unlike pg_duckdb and pg_analytics, pg_mooncake can write out data to Iceberg or Delta Lake formats via transactional INSERT/UPDATE/DELETE.

That's a cool demo you're building using ddlog! FWIW, we, the ddlog team have moved on to found feldera.com (https://github.com/feldera/feldera). You could consider using DBSP directly through Rust.

Raphtory
Scalable graph analytics database powered by a multithreaded, vectorized temporal engine, written in Rust
Project mention: Show HN: HelixDB – Open-Source Vector-Graph Database for AI Applications (Rust) | news.ycombinator.com | 2025-05-13Shameless plug: If you're exploring graph+vector databases, check out https://github.com/Pometry/Raphtory/ — with a full Python SDK and built-in support for most common graph algorithms.
It’s built in Rust with native vector support. The open-source version is in-memory, but the commercial version supports disk-based scaling (we tested it with a 3TB graph on an M1 MacBook + insert all 100x faster than existing GraphDBs).
