If using a source distribution rather than a wheel, Cython is used to compile certain parts of the driver. This makes those hot paths faster at runtime, but the Cython compilation process can take a long time -- as long as 10 minutes in some environments. In environments where performance is less important, it may be worth it to :ref:`disable Cython as documented below <cython-extensions>`. -You can also use ``CASS_DRIVER_BUILD_CONCURRENCY`` to increase the number of -threads used to build the driver and any C extensions: - -.. code-block:: bash - $ # installing from source - $ CASS_DRIVER_BUILD_CONCURRENCY=8 python setup.py install - $ # installing from pip - $ CASS_DRIVER_BUILD_CONCURRENCY=8 pip install cassandra-driver +Cython also supports concurrent builds of native extensions. The ``build-concurrency`` key in the +``tool.cassandra-driver`` table of pyproject.toml is an integer value which specifies the number of +concurrent builds Cython may execute. The value for this key must be a non-negative integer; the default is zero, +indicating no concurrent builds. The ``multiprocessing`` module must be installed if concurrent builds are used.
