class airflow.contrib.operators.gcp_bigtable_operator.BigtableInstanceCreateOperator(instance_id, main_cluster_id, main_cluster_zone, project_id=None, replica_cluster_id=None, replica_cluster_zone=None, instance_display_name=None, instance_type=None, instance_labels=None, cluster_nodes=None, cluster_storage_type=None, timeout=None, gcp_conn_id='google_cloud_default', *args, **kwargs)[source]

Bases: airflow.models.BaseOperator, airflow.contrib.operators.gcp_bigtable_operator.BigtableValidationMixin

Creates a new Cloud Bigtable instance. If the Cloud Bigtable instance with the given ID exists, the operator does not compare its configuration and immediately succeeds. No changes are made to the existing instance.

For more details about instance creation have a look at the reference: https://googleapis.github.io/google-cloud-python/latest/bigtable/instance.html#google.cloud.bigtable.instance.Instance.create

Parameters

  • instance_id (str) – The ID of the Cloud Bigtable instance to create.

  • main_cluster_id (str) – The ID for main cluster for the new instance.

  • main_cluster_zone (str) – The zone for main cluster See https://cloud.google.com/bigtable/docs/locations for more details.

  • project_id (str) – Optional, the ID of the GCP project. If set to None or missing, the default project_id from the GCP connection is used.

  • replica_cluster_id (str) – (optional) The ID for replica cluster for the new instance.

  • replica_cluster_zone (str) – (optional) The zone for replica cluster.

  • instance_type (enums.IntEnum) – (optional) The type of the instance.

  • instance_display_name (str) – (optional) Human-readable name of the instance. Defaults to instance_id.

  • instance_labels (dict) – (optional) Dictionary of labels to associate with the instance.

  • cluster_nodes (int) – (optional) Number of nodes for cluster.

  • cluster_storage_type (enums.IntEnum) – (optional) The type of storage.

  • timeout (int) – (optional) timeout (in seconds) for instance creation. If None is not specified, Operator will wait indefinitely.
