    Client

    Parent client for calling the Google Cloud Bigtable API.

    This is the base from which all interactions with the API occur.

    In the hierarchy of API concepts

    google.cloud.bigtable.client.ADMIN_SCOPE( = ' https://www.googleapis.com/auth/bigtable.admin )

    Scope for interacting with the Cluster Admin and Table Admin APIs.

    class google.cloud.bigtable.client.Client(project=None, credentials=None, read_only=False, admin=False, client_info=None, client_options=None, admin_client_options=None, channel=None)

    Bases: google.cloud.client.ClientWithProject

    Client for interacting with Google Cloud Bigtable API.

    NOTE: Since the Cloud Bigtable API requires the gRPC transport, no _http argument is accepted by this class.

    • Parameters

      • project( str or unicode ) – (Optional) The ID of the project which owns the instances, tables and data. If not provided, will attempt to determine from the environment.

      • credentials( Credentials ) – (Optional) The OAuth2 Credentials to use for this client. If not passed, falls back to the default inferred from the environment.

      • read_only( bool ) – (Optional) Boolean indicating if the data scope should be for reading only (or for writing as well). Defaults to False .

      • admin( bool ) – (Optional) Boolean indicating if the client will be used to interact with the Instance Admin or Table Admin APIs. This requires the ADMIN_SCOPE . Defaults to False .

      • client_info– The client info used to send a user-agent string along with API requests. If None , then default info will be used. Generally, you only need to set this if you’re developing your own library or partner tool.

      • client_options( ClientOptions or dict ) – (Optional) Client options used to set user options on the client. API Endpoint should be set through client_options.

      • admin_client_options( ClientOptions or dict ) – (Optional) Client options used to set user options on the client. API Endpoint for admin operations should be set through admin_client_options.

      • ( grpc.Channel )( channel ) – (Optional) DEPRECATED: A Channel instance through which to make calls. This argument is mutually exclusive with credentials ; providing both will raise an exception. No longer used.

    • Type

      client_info: google.api_core.gapic_v1.client_info.ClientInfo

    • Raises

      ValueError if both read_only and admin are True

    instance(instance_id, display_name=None, instance_type=None, labels=None)

    Factory to create a instance associated with this client.

    For example:

     from google.cloud.bigtable import Client 
from google.cloud.bigtable import enums

my_instance_id = "inst-my-" + UNIQUE_SUFFIX
my_cluster_id = "clus-my-" + UNIQUE_SUFFIX
location_id = "us-central1-f"
serve_nodes = 1
storage_type = enums. StorageType 
.SSD
production = enums.Instance.Type.PRODUCTION
labels = {"prod-label": "prod-label"}

client = Client(admin=True)
instance = client 
. instance 
(my_instance_id, instance_type=production, labels=labels)
cluster = instance.cluster(
    my_cluster_id,
    location_id=location_id,
    serve_nodes=serve_nodes,
    default_storage_type=storage_type,
)
operation = instance.create(clusters=[cluster])

# We want to make sure the operation completes.
operation.result(timeout=100)

    • Parameters

      • instance_id( str ) – The ID of the instance.

      • display_name( str ) – (Optional) The display name for the instance in the Cloud Console UI. (Must be between 4 and 30 characters.) If this value is not set in the constructor, will fall back to the instance ID.

      • instance_type( int ) – (Optional) The type of the instance. Possible values are represented by the following constants: google.cloud.bigtable.instance.InstanceType.PRODUCTION . google.cloud.bigtable.instance.InstanceType.DEVELOPMENT , Defaults to google.cloud.bigtable.instance.InstanceType.UNSPECIFIED .

      • labels( dict ) – (Optional) Labels are a flexible and lightweight mechanism for organizing cloud resources into groups that reflect a customer’s organizational needs and deployment strategies. They can be used to filter resources and aggregate metrics. Label keys must be between 1 and 63 characters long. Maximum 64 labels can be associated with a given resource. Label values must be between 0 and 63 characters long. Keys and values must both be under 128 bytes.

    • Return type

      Instance

    • Returns

      an instance owned by this client.

    property instance_admin_client()

    Getter for the gRPC stub used for the Table Admin API.

    For example:

     from google.cloud.bigtable import Client 
client = Client(admin=True)
instance_admin_client = client 
.instance_admin_client

    • Return type

      bigtable_admin_pb2.BigtableInstanceAdmin

    • Returns

      A BigtableInstanceAdmin instance.

    • Raises

      ValueError if the current client is not an admin client or if it has not been start() -ed.

    list_clusters()

    List the clusters in the project.

    For example:

     from google.cloud.bigtable import Client 
client = Client(admin=True)
(clusters_list, failed_locations_list) = client 
. list_clusters 
()

    • Return type

      tuple

    • Returns

      (clusters, failed_locations), where ‘clusters’ is list of google.cloud.bigtable.instance.Cluster , and ‘failed_locations’ is a list of strings representing locations which could not be resolved.

    list_instances()

    List instances owned by the project.

    For example:

     from google.cloud.bigtable import Client 
client = Client(admin=True)
(instances_list, failed_locations_list) = client 
. list_instances 
()

    property project_path()

    Project name to be used with Instance Admin API.

    NOTE: This property will not change if project does not, but the return value is not cached.

    For example:

     from google.cloud.bigtable import Client 
client = Client(admin=True)
project_path = client 
. project_path

    The project name is of the form

    "projects/{project}"

    • Return type

      str

    • Returns

      Return a fully-qualified project string.

    property table_admin_client()

     from google.cloud.bigtable import Client 
client = Client(admin=True)
table_admin_client = client 
. table_admin_client

    • Return type

      bigtable_admin_pb2.BigtableTableAdmin

    • Returns

      A BigtableTableAdmin instance.

    • Raises

      ValueError if the current client is not an admin client or if it has not been start() -ed.

    property table_data_client()

    Getter for the gRPC stub used for the Table Admin API.

    For example:

     from google.cloud.bigtable import Client

table_data_client = client 
. table_data_client

    • Return type

      bigtable_v2.BigtableClient

    • Returns
