upgrade:
- |
oslo.db now logs a warning when the connection URL does not
explicitly mention a driver. The default driver is still used, but
in some cases, such as MySQL, the default is incompatible with the
concurrency library eventlet.
- |
It is strongly recommended to use the `PyMySQL
<https://pypi.python.org/pypi/PyMySQL>`__ driver when connecting
to a MySQL-compatible database to ensure the best compatibility
with the concurrency library eventlet. To use PyMySQL, ensure the
connection URL is specified with ``mysql+pymysql://`` as the
scheme.
