Drizzle-Python is available at:
http://sourceforge.net/projects/mysql-python
At least version 1.2.1 or 1.2.2 should be used.
Connecting
-----------
Connect string format::
drizzle+mysqldb://<user>:<password>@<host>[:<port>]/<dbname>
Unicode
-------
Drizzle accommodates Python ``unicode`` objects directly and
uses the ``utf8`` encoding in all cases.
Known Issues
-------------
Drizzle-python at least as of version 1.2.2 has a serious memory leak related
to unicode conversion, a feature which is disabled via ``use_unicode=0``.
The recommended connection form with SQLAlchemy is::
engine = create_engine('mysql://scott:tiger@localhost/test?charset=utf8&use_unicode=0', pool_recycle=3600)
