.. dialect:: firebird+kinterbasdb
    :name: kinterbasdb
    :dbapi: kinterbasdb
    :connectstring: firebird+kinterbasdb://user:password@host:port/path/to/db[?key=value&key=value...]
    :url: https://firebirdsql.org/index.php?op=devel&sub=python

Arguments
----------

The Kinterbasdb backend accepts the ``enable_rowcount`` and ``retaining``
arguments accepted by the :mod:`sqlalchemy.dialects.firebird.fdb` dialect.
In addition, it also accepts the following:

* ``type_conv`` - select the kind of mapping done on the types: by default
  SQLAlchemy uses 200 with Unicode, datetime and decimal support.  See
  the linked documents below for further information.

* ``concurrency_level`` - set the backend policy with regards to threading
  issues: by default SQLAlchemy uses policy 1.  See the linked documents
  below for further information.
