Simple demo for using data-diff with MySQL and BigQuery, to keep for future reference.
Careful: as of 24 October, 2022, there is an issue with mysql-connector-python and it has to be downgraded to version 8.0.29; see my comment. But they are working on it.
Things missing from the repo for security: .env and gcloud_key_tzanakis-bigquery.json.
