duckdb-adbc

The adbc extension lets DuckDB (v1.4.5+ or v1.5.4+) query any database that has an ADBC (Arrow Database Connectivity) driver — Snowflake, Databricks, BigQuery, PostgreSQL, MySQL, and more — directly from SQL, using zero-copy Arrow data transfer instead of legacy row-based APIs like ODBC/JDBC.

Prerequisites

1. Install the extension

From within a DuckDB session (or a .sql file / -c invocation):

INSTALL adbc FROM community;
LOAD adbc;

If DuckDB reports it can't find the extension, confirm the DuckDB version is 1.4.5+ (or 1.5.4+) — the extension requires a recent build.
