We just shipped our official ADBC driver, in partnership with @columnar_tech. clickhou.se/4gx3nwq One command installs a signed binary, and it speaks Apache Arrow natively, so results move from ClickHouse into your app with zero conversion. Ruby, R, and C get real ClickHouse access for the first time.
