Bases: airflow.contrib.operators.gcp_sql_operator.CloudSqlBaseOperator

Exports data from a Cloud SQL instance to a Cloud Storage bucket as a SQL dump or CSV file.

Note: This operator is idempotent. If executed multiple times with the same export file URI, the export file in GCS will simply be overridden.

Parameters

  • instance (str) – Cloud SQL instance ID. This does not include the project ID.

  • body (dict) – The request body, as described in https://cloud.google.com/sql/docs/mysql/admin-api/v1beta4/instances/export#request-body

Bases: airflow.contrib.operators.gcp_sql_operator.CloudSqlBaseOperator

Imports data into a Cloud SQL instance from a SQL dump or CSV file in Cloud Storage.

CSV IMPORT:

This operator is NOT idempotent for a CSV import. If the same file is imported multiple times, the imported data will be duplicated in the database. Moreover, if there are any unique constraints the duplicate import may result in an error.

SQL IMPORT:

This operator is idempotent for a SQL import if it was also exported by Cloud SQL. The exported SQL contains ‘DROP TABLE IF EXISTS’ statements for all tables to be imported.

If the import file was generated in a different way, idempotence is not guaranteed. It has to be ensured on the SQL file level.

Parameters

  • instance (str) – Cloud SQL instance ID. This does not include the project ID.

  • body (dict) – The request body, as described in https://cloud.google.com/sql/docs/mysql/admin-api/v1beta4/instances/export#request-body

  • project_id (str) – Optional, Google Cloud Platform Project ID. If set to None or missing, the default project_id from the GCP connection is used.

  • gcp_conn_id (str) – The connection ID used to connect to Google Cloud Platform.

  • api_version (str) – API version used (e.g. v1beta4).

  • validate_body (bool) – Whether the body should be validated. Defaults to True.

Bases: airflow.models.BaseOperator

Performs DML or DDL query on an existing Cloud Sql instance. It optionally uses cloud-sql-proxy to establish secure connection with the database.

See also

For more information on how to use this operator, take a look at the guide: CloudSqlQueryOperator

Parameters

  • sql (str or list[str]) – SQL query or list of queries to run (should be DML or DDL query - this operator does not return any data from the database, so it is useless to pass it DQL queries. Note that it is responsibility of the author of the queries to make sure that the queries are idempotent. For example you can use CREATE TABLE IF NOT EXISTS to create a table.

  • parameters (mapping or iterable) – (optional) the parameters to render the SQL query with.

  • autocommit (bool) – if True, each command is automatically committed. (default value: False)

  • gcp_conn_id (str) – The connection ID used to connect to Google Cloud Platform for cloud-sql-proxy authentication.

  • gcp_cloudsql_conn_id (str) – The connection ID used to connect to Google Cloud SQL its schema should be gcpcloudsql://. See CloudSqlDatabaseHook for details on how to define gcpcloudsql:// connection.
