Revision history for DBIO-DuckDB

0.900000  2026-06-23
    First release. DuckDB driver for DBIO built on the pure-FFI DBD::DuckDB.

    * Storage
        - DBIO::DuckDB schema component; autodetects dbi:DuckDB: DSNs and
          forces +DBIO::DuckDB::Storage
        - DBIO::DuckDB::Storage on DBIO::Storage::DBI: double-quoted
          identifiers, INSERT ... RETURNING, savepoints
        - `-du` shortcut (use DBIO Schema => -du) via DBIO::Shortcut::du

    * SQLMaker
        - DBIO::DuckDB::SQLMaker: PostgreSQL-flavored dialect, disables
          SELECT ... FOR UPDATE

    * DDL / Deploy
        - DBIO::DuckDB::DDL generates DuckDB DDL from Result classes via a
          single-source emitter (DBIO::DuckDB::DDL::Emit)
        - emits CREATE VIEW for non-virtual views (from view_definition),
          after all tables
        - DBIO::DuckDB::Deploy installs and upgrades schemas via native
          test-deploy-and-compare

    * Introspect / Diff
        - DBIO::DuckDB::Introspect reads information_schema and duckdb_*
          views (tables, columns, indexes, foreign keys)
        - DBIO::DuckDB::Diff compares two introspected models (tables,
          columns, indexes)

    * DuckDB specials
        - Arrow-fetch and Appender escape hatches for columnar / bulk paths
        - read_csv / read_parquet / read_json table-function helpers
        - extension install, checkpoint, version helpers
        - Quack client-server RPC (libduckdb >= 1.5): quack_serve,
          quack_attach, quack_detach, plus on-connect attach hook

    * Tests
        - TAP suite: 00-load, 08-shortcut, 10-smoke, 20-introspect,
          21-introspect-contract, 30-deploy, 35-ddl-emit, 40-diff,
          50-arrow, 60-quack
