SlothDB is a from-scratch C++20 embedded SQL database in active development. Same model as DuckDB and SQLite: query Parquet, CSV, JSON, Arrow, Avro, SQLite, and Excel files directly with SQL, in-process. Early-stage; read the Status section below before treating any performance numbers as final. Website · Playground · Discord · Blog · Docs · Benchmarks · Python · SQL Guide --- Status SlothDB is early-stage and experimental. - No vendor PR to ClickBench is open or planned while the handler dispatch is still there. Treat performance numbers in this README as anecdotal until the architecture work lands. The project is a learning exercise; expect rough edges. --- Ask in any language. Get SQL. Type .ask at the slothdb prompt. A rules parser handles catalog questions and common English shapes in under 10 ms with no model. Anything else falls through to a local Qwen2.5-Coder (0.5B for simple, 1.5B for analytic; lazy-downloaded on first use under -DSLOTHDB ASK MODEL=ON ), which speaks 29 natural languages: English, Chinese, Spanish, French, German, Japanese, Korean, Russian, Arabic, Portuguese, Italian, Hindi, and more. Every generated statement is shown before it runs. Nothing leaves the machine.
