Changes

0.1.0 (unreleased)

Initial release.

• duckdb.types: next.jdbc protocol extensions so DuckDB LIST / STRUCT / MAP columns round-trip as Clojure vectors and maps, recursively, in both directions. STRUCT fields keywordized on read and bound positionally on write (absent keys throw); MAP keys keep their natural type. Untyped parameters fall back to raw binding.
• duckdb.core: memory-datasource / file-datasource, read-parquet / read-csv with validated named options, attach! / detach!, install-extension! / load-extension!, duckdb-version.
