DuckDB — in-process columnar OLAP SQL engine in a single binary ("SQLite for analytics"). Use when querying Parquet/CSV/JSON files directly with SQL, using the `duckdb` CLI shell (REPL or `-c`/`-json` one-shots), friendly SQL (FROM-first, `SELECT * EXCLUDE`, `GROUP BY ALL`, `SUMMARIZE`, `PIVOT`), converting CSV↔Parquet↔JSON via `COPY`, reading HTTP/S3 via httpfs, or `ATTACH`-ing Postgres/MySQL/SQLite. Includes `(duckdb vX.Y+)` annotations; the CLI/SQL engine, not client libraries.
