@potiuk Could you assign someone to review?

[mik-laj]

To add support for sqlalchemy-spanner, we should also add get_uri method.

airflow/airflow/providers/snowflake/hooks/snowflake.py

Lines 216 to 219 in 33edeb2

	def get_uri(self) -> str:
	"""Override DbApiHook get_uri method for get_sqlalchemy_engine()"""
	conn_params = self._get_conn_params()
	return self._conn_params_to_sqlalchemy_uri(conn_params)

[potiuk]

Rebased it to latest main - let's see if it works.

[lwyszomi]

@potiuk @mik-laj I was offline most of the week, Thanks for feedback I will update my PR in this week.

[lwyszomi]

@mik-laj When we add get_uri method we should also extend this hook and add inheritance from DbApiHook?

[mik-laj]

@lwyszomi , Yes. Thanks to this, we will be able to use it in other places where DBApiHook class is expected. Users will also not need to study this class specifically, as they will be able to rely on a unified interface.

[lwyszomi]

@mik-laj I have one more think in my mind, if we extend this hook maybe by default we should add sqlalchemy-spanner to the google provider packages, WDYT?

[mik-laj]

@lwyszomi Yes. We should do it. Thanks to this, we will avoid dependency conflicts, because problems will be detected on the CI.

airflow/setup.py

Lines 513 to 516 in 774ca08

	snowflake = [
	'snowflake-connector-python>=2.4.1',
	'snowflake-sqlalchemy>=1.1.0',
	]

[potiuk]

Yep. Good idea.

@potiuk @mik-laj This change for now is blocked because we have a issue with the dependencies. The Airflow supporting sqlalchemy<1.4.10,>=1.4 but sqlalchemy-spanner supporting sqlalchemy<=1.3.23,>=1.1.13. Conflict for now cannot be resolved, we need to wait when sqlalchemy-spanner will support sqlalchemy<1.4.10,>=1.4.

Too bad. I opened issue for that: googleapis/python-spanner-sqlalchemy#204

[lwyszomi]

@potiuk thanks

[potiuk]

Apparently, support (and test case suite) was added in January but the setup.py has not been updated :)

googleapis/python-spanner-sqlalchemy#204 (comment)

@lwyszomi - seems like Google Spanner now suports sqlalchemy 1.4 googleapis/python-spanner-sqlalchemy#204 - feel free to provide support for it :)
