SQL over Parquet files for evening market research. Educational only. Not investment advice.
Map for SQL-on-DataFrame after work: Polars SQL, SQLGlot, DuckDB, SQLFrame, Ibis. Anchored on Polars 1.44.2 + SQLGlot 30.18 freshness—not DuckDB 2.0 / Polars Iceberg / Polars 2.0 RC retreads. Educational only. Not investment advice.
Official DuckDB v2.0 preview (17 Aug 2026): new parser, storage, and server mode. After-work analysts on CSV/Parquet should stay in-process, pick 1.4 LTS vs 1.5 from the calendar, and back up before 2.0. Spark is not required.
