Google Cloud BigQuery Transfer Operator to MySQL

Google Cloud BigQuery is Google Cloud’s serverless data warehouse offering. MySQL is an open-source relational database management system. This operator can be used to copy data from a BigQuery table to MySQL.

Prerequisite Tasks

To use these operators, you must do a few things:

Operator

Copying data from one BigQuery table to another is performed with the BigQueryToMySqlOperator operator.

Use Jinja templating with target_table_name, impersonation_chain, dataset_id, table_id to define values dynamically.

You may use the parameter selected_fields to limit the fields to be copied (all fields by default), as well as the parameter replace to overwrite the destination table instead of appending to it. For more information, please refer to the links above.

Transferring data

The following Operator copies data from a BigQuery table to MySQL.

    task_id="bigquery_to_mysql",
    dataset_table=f"{DATASET_NAME}.{TABLE}",
    target_table_name=destination_table,
    replace=False,
)
