Understanding registry.register()

[Terrence Brannon]

hello, I am trying to understand the following code from sqlalchemy-drill:

from sqlalchemy.dialects import registry
	registry.register("drill", "sqlalchemy_drill.sadrill", "DrillDialect_sadrill")
	registry.register("drill.sadrill", "sqlalchemy_drill.sadrill", "DrillDialect_sadrill")
	registry.register("drill.jdbc", "sqlalchemy_drill.jdbc", "DrillDialect_jdbc")

and in looking over sqlalchemy.dialects one can see that registry is an instance of util.PluginLoader:

registry = util.PluginLoader("sqlalchemy.dialects", auto_fn=_auto_fn)

However, none of that makes it clear to me what the 3 arguments to .register() above represent.

If there is documentation on this subject, I would appreciate being pointed to it.

If there is documentation in the code on this subject please point me to it and accept my apologies.

3rd party dialect documentation is at https://github.com/sqlalchemy/sqlalchemy/blob/master/README.dialects.rst

the drill dialect shouldn't have to have that registry logic in their __init__.py, it's documented as being used for the test suite in conftest.py.   see the above document for guidelines.
