-.. dialect:: mysql+gaerdbms
-    :name: Google Cloud SQL
-    :dbapi: rdbms

-    :url: https://developers.google.com/appengine/docs/python/cloud-sql/developers-guide
-
-    This dialect is based primarily on the :mod:`.mysql.mysqldb` dialect with
-    minimal changes.
-
-    .. deprecated:: 1.0 This dialect is **no longer necessary** for
-        Google Cloud SQL; the MySQLdb dialect can be used directly.
-        Cloud SQL now recommends creating connections via the
-        mysql dialect using the URL format
-
-        ``mysql+mysqldb://root@/<dbname>?unix_socket=/cloudsql/<projectid>:<instancename>``
-
-
-Pooling
--------
-
-Google App Engine connections appear to be randomly recycled,
-so the dialect does not pool connections.  The :class:`.NullPool`
-implementation is installed within the :class:`.Engine` by
-default.
