This starter kit is to connect to Google's BigQuery. You can use Data Manipulation Language (DML) since this uses jobs.query of bigquery API. The reason why this uses jobs.query to insert data rather than streaming insert api is to allow the inserted data to be modified immediately.
Put your GCP project information in the [bigquery] section of the src/config.toml file. You will need a service account for your project to connect BigQuery.
