Database-Specific Adapter Options

Each adapter supports one common option:

driver

The name of the driver to use for this database. Defaults to “auto”, meaning to choose the best driver from among the possibilities. Most of the time this option should be omitted and RelStorage will choose the best option.

This is handy to set when an environment might have multiple drivers installed, some of which might be non-optimal. For example, on PyPy, PyMySQL is generally faster than MySQLdb, but both can be installed (in the form of mysqlclient for the latter).

This is also convenient when using zodbshootout to compare driver speeds.

If you specify a driver that is not installed, an error will be raised.

Each adapter will document the available driver names.
