Deletes a database from the specified Cloud Spanner instance. If the database does not exist, no action is taken, and the operator succeeds.
For parameter definition, take a look at ~airflow.contrib.operators.gcp_spanner_operator.CloudSpannerInstanceDatabaseDeleteOperator.
Some arguments in the example DAG are taken from environment variables.
../../../../airflow/contrib/example_dags/example_gcp_spanner.py
You can create the operator with or without project id. If project id is missing it will be retrieved from the GCP connection used. Both variants are shown:
../../../../airflow/contrib/example_dags/example_gcp_spanner.py
../../../../airflow/contrib/operators/gcp_spanner_operator.py
See Google Cloud Spanner API documentation to drop an instance of a database.
Creates a new Cloud Spanner database in the specified instance, or if the desired database exists, assumes success with no changes applied to database configuration. No structure of the database is verified - it's enough if the database exists with the same name.
For parameter definition, take a look at ~airflow.contrib.operators.gcp_spanner_operator.CloudSpannerInstanceDatabaseDeployOperator.
Some arguments in the example DAG are taken from environment variables.

../../../../airflow/contrib/example_dags/example_gcp_spanner.py
../../../../airflow/contrib/operators/gcp_spanner_operator.py
See Google Cloud Spanner API documentation to create a new database.
Runs a DDL query in a Cloud Spanner database and allows you to modify the structure of an existing database.
You can optionally specify an operation_id parameter which simplifies determining whether the statements were executed in case the update_database call is replayed (idempotency check). The operation_id should be unique within the database, and must be a valid identifier: [a-z][a-z0-9_]*. More information can be found in the documentation of updateDdl API
For parameter definition take a look at ~airflow.contrib.operators.gcp_spanner_operator.CloudSpannerInstanceDatabaseUpdateOperator.

See Google Cloud Spanner API documentation for database update_ddl.
Executes an arbitrary DML query (INSERT, UPDATE, DELETE).
For parameter definition take a look at ~airflow.contrib.operators.gcp_spanner_operator.CloudSpannerInstanceDatabaseQueryOperator.
Some arguments in the example DAG are taken from environment variables.
../../../../airflow/contrib/example_dags/example_gcp_spanner.py

See Google Cloud Spanner API documentation for more information about DML syntax.
Deletes a Cloud Spanner instance. If an instance does not exist, no action is taken, and the operator succeeds.
