Thank you for opening a Pull Request! Before submitting your PR, there are a few things you can do to make sure it goes smoothly:

  • Make sure to open an issue as a bug/issue before writing your code! That way we can discuss the change, evaluate designs, and agree on the general idea
  • Ensure the tests and linter pass
  • Code coverage does not decrease (if any source code was changed)
  • Appropriate docs were updated (if necessary)

Fixes #231 🦕

I added a "do not merge" tag, because I'm not sure we want people to do this.

However, I'd kind of like to know how to do samples, and would like some feedback. :)

These look good! I think we just need to adjust the tags so that the snippet bot is happy.

Because of the way we track samples, the tag needs to start with the API name.

How about bigquery_geopandas_sqlalchemy ?

Needs to start with bigquery, how about bigquery_pandas_sqlalchemy?

Kokoro failure looks like a flake by the backend. I learned that the backend can take as long as 4 minutes to fail on some API requests, so hopefully googleapis/python-bigquery#859 helps with this.

google.api_core.exceptions.RetryError: Deadline of 120.0s exceeded while calling functools.partial(functools.partial(<bound method JSONConnection.api_request of <google.cloud.bigquery._http.Connection object at 0x7fe2a9e0e970>>, method='GET', path='/projects/precise-truck-742/queries/0aba5d5e-abdb-415a-9ffd-ad2aa450ad59', query_params={'maxResults': 0, 'location': 'US'}, timeout=None)), last exception: 500 GET https://bigquery.googleapis.com/bigquery/v2/projects/precise-truck-742/queries/0aba5d5e-abdb-415a-9ffd-ad2aa450ad59?maxResults=0&location=US&prettyPrint=false: An internal error occurred and the request could not be completed.

In the meantime, I'll manually trigger the Kokoro job to rebuild.

Yup, I figured.

Cool, but remember the goal of this PR, at least for me, was to get a grip on samples. :)

It's been super helpful, but I don't intend to merge it.

IMO, these samples are counter productive, because, as you've noted, the BQ python libary's to_dataset (and soon, to_geodataset) is more performant and scalable. Of course, if you disagree, I'm happy to defer.

My thought is when to_geodataset lands (googleapis/python-bigquery#848 is ready for review, BTW :) ), I'd make a GeoPandas PR to add from_bigquery and to_bigquery using to_geodataframe and load_from_dataframe.

I've merged this into the geography branch and deleted these two examples (and added a geography sample).

If you really want these samples, let me know and I'll reopen this.
