…a federated query against Cloud SQL

Problem:
The BigQuery documentation (https://cloud.google.com/bigquery/docs/cloud-sql-federated-queries) needs a standalone, tested Python code sample demonstrating how to run a federated query against Cloud SQL (region tag bigquery_federated_query_cloud_sql).

Solution:

  • Add federated_query_cloud_sql(project_id: str, connection_id: str) -> None in bigquery/federated_queries/bigquery_federated_query_cloud_sql.py (Query a relational table in Cloud SQL in real time from BigQuery using EXTERNAL_QUERY.)
  • Add unit tests (bigquery/federated_queries/bigquery_federated_query_cloud_sql_test.py) covering both the success path and API error handling (GoogleAPICallError)

Code Review

This pull request introduces a new Python sample for running federated queries from BigQuery to Cloud SQL using EXTERNAL_QUERY, along with its corresponding unit tests and configuration files. The feedback suggests updating the ignored_versions in noxfile_config.py to align with the repository's policy of testing only the oldest and newest supported Python versions (3.10 and 3.13) while ignoring intermediate versions.
