I Built an Apache Arrow ADBC Driver for Every ODBC Database: 46 Databases, 5 Languages, Every Number Measured
Native Apache Arrow ADBC drivers exist for a handful of databases. The other few hundred ship an ODBC driver and nothing else. adbcBridge is one plain-C11 shared library that turns every ODBC driver on your machine into an Arrow-native ADBC driver — columnar record batches out, bulk ingest in — from Python, Rust, Go, Java and C#. Today it is public: 46 databases verified on Linux, 41 on macOS, 45 on Windows, five languages measured against all of them, and every figure named with the laptop and the load it was taken under.
