adbc-driver-flightsql

ADBC Apache Arrow Flight SQL Driver for Python

This package contains bindings for the Golang Apache Arrow Flight SQL driver, using the driver manager to provide a DBAPI 2.0/PEP 249-compatible interface on top.

Building

Dependencies: a build of the Apache Arrow Flight SQL driver, and the adbc-driver-manager Python package. Optionally, install PyArrow to use the DBAPI 2.0-compatible interface.

Set the environment variable ADBC_FLIGHTSQL_LIBRARY to the path to libadbc_driver_flightsql.{dll,dylib,so} before running pip install.

# If not already installed
pip install -e ../adbc_driver_manager

export ADBC_FLIGHTSQL_LIBRARY=/path/to/libadbc_driver_flightsql.so
pip install --no-deps -e .

For users building from the arrow-adbc source repository, you can alternately use CMake to manage library dependencies and set environment variables for you. Assuming you specify -DADBC_DRIVER_FLIGHTSQL=ON you can also add -DADBC_BUILD_PYTHON=ON to define a python target.

For example, assuming you run cmake from the project root:

cmake -S c -B build --preset debug -DADBC_BUILD_PYTHON=ON -DADBC_DRIVER_FLIGHTSQL=ON
cmake --build build --target python

will properly build and install the Python library for you.

See CONTRIBUTING.md for details on the general build process.

Testing

To run the tests, use pytest:

$ pytest -vvx
