Class DataprocMetastoreAsyncClient (0.1.0)

DataprocMetastoreAsyncClient(*, credentials: google.auth.credentials.Credentials = None, transport: Union[str, google.cloud.metastore_v1beta.services.dataproc_metastore.transports.base.DataprocMetastoreTransport] = 'grpc_asyncio', client_options: <module 'google.api_core.client_options' from '/workspace/python-dataproc-metastore/.nox/docfx/lib/python3.9/site-packages/google/api_core/client_options.py'> = None, client_info: google.api_core.gapic_v1.client_info.ClientInfo = <google.api_core.gapic_v1.client_info.ClientInfo object>)

Configures and manages metastore services. Metastore services are fully managed, highly available, auto-scaled, auto-healing, OSS-native deployments of technical metadata management software. Each metastore service exposes a network endpoint through which metadata queries are served. Metadata queries can originate from a variety of sources, including Apache Hive, Apache Presto, and Apache Spark.

The Dataproc Metastore API defines the following resource model:

The service works with a collection of Google Cloud projects, named: /projects/*
Each project has a collection of available locations, named: /locations/* (a location must refer to a Google Cloud region)
Each location has a collection of services, named: /services/*
Dataproc Metastore services are resources with names of the form:

/projects/{project_number}/locations/{location_id}/services/{service_id}.

Properties

transport

Return the transport used by the client instance.

Returns
Type	Description
`DataprocMetastoreTransport`	The transport used by the client instance.

Methods

DataprocMetastoreAsyncClient

DataprocMetastoreAsyncClient(*, credentials: google.auth.credentials.Credentials = None, transport: Union[str, google.cloud.metastore_v1beta.services.dataproc_metastore.transports.base.DataprocMetastoreTransport] = 'grpc_asyncio', client_options: <module 'google.api_core.client_options' from '/workspace/python-dataproc-metastore/.nox/docfx/lib/python3.9/site-packages/google/api_core/client_options.py'> = None, client_info: google.api_core.gapic_v1.client_info.ClientInfo = <google.api_core.gapic_v1.client_info.ClientInfo object>)

Instantiate the dataproc metastore client.

Parameters
Name	Description
`credentials`	`Optional[google.auth.credentials.Credentials]` The authorization credentials to attach to requests. These credentials identify the application to the service; if none are specified, the client will attempt to ascertain the credentials from the environment.
`transport`	`Union[str, .DataprocMetastoreTransport]` The transport to use. If set to None, a transport is chosen automatically.
`client_options`	`ClientOptions` Custom options for the client. It won't take effect if a `transport` instance is provided. (1) The `api_endpoint` property can be used to override the default endpoint provided by the client. GOOGLE_API_USE_MTLS_ENDPOINT environment variable can also be used to override the endpoint: "always" (always use the default mTLS endpoint), "never" (always use the default regular endpoint) and "auto" (auto switch to the default mTLS endpoint if client certificate is present, this is the default value). However, the `api_endpoint` property takes precedence if provided. (2) If GOOGLE_API_USE_CLIENT_CERTIFICATE environment variable is "true", then the `client_cert_source` property can be used to provide client certificate for mutual TLS transport. If not provided, the default SSL client certificate will be used if present. If GOOGLE_API_USE_CLIENT_CERTIFICATE is "false" or not set, no client certificate will be used.

Exceptions
Type	Description
`google.auth.exceptions.MutualTlsChannelError`	If mutual TLS transport creation failed for any reason.
