Dataproc Metastore API v1 - Package cloud.google.com/go/metastore/apiv1 (v0.86.0)

Package metastore is an auto-generated package for the Dataproc Metastore API.

The Dataproc Metastore API is used to manage the lifecycle and configuration of metastore services.

Use of Context

The ctx passed to NewClient is used for authentication requests and for creating the underlying connection, but is not used for subsequent calls. Individual methods on the client use the ctx given to them.

To close the open connection, use the Close() method.

For information about setting deadlines, reusing contexts, and more please visit https://pkg.go.dev/cloud.google.com/go.

Functions

func DefaultAuthScopes

func DefaultAuthScopes() []string

DefaultAuthScopes reports the default set of authentication scopes to use with this package.

CreateMetadataImportOperation

type CreateMetadataImportOperation struct {
	// contains filtered or unexported fields
}

CreateMetadataImportOperation manages a long-running operation from CreateMetadataImport.

func (*CreateMetadataImportOperation) Done

Done reports whether the long-running operation has completed.

func (*CreateMetadataImportOperation) Metadata

Metadata returns metadata associated with the long-running operation. Metadata itself does not contact the server, but Poll does. To get the latest metadata, call this method after a successful call to Poll. If the metadata is not available, the returned metadata and error are both nil.

func (*CreateMetadataImportOperation) Name

Name returns the name of the long-running operation. The name is assigned by the server and is unique within the service from which the operation is created.

func (*CreateMetadataImportOperation) Poll

Poll fetches the latest state of the long-running operation.

Poll also fetches the latest metadata, which can be retrieved by Metadata.

If Poll fails, the error is returned and op is unmodified. If Poll succeeds and the operation has completed with failure, the error is returned and op.Done will return true. If Poll succeeds and the operation has completed successfully, op.Done will return true, and the response of the operation is returned. If Poll succeeds and the operation has not completed, the returned response and error are both nil.

func (*CreateMetadataImportOperation) Wait

Wait blocks until the long-running operation is completed, returning the response and any errors encountered.

See documentation of Poll for error-handling information.

CreateServiceOperation

type CreateServiceOperation struct {
	// contains filtered or unexported fields
}

CreateServiceOperation manages a long-running operation from CreateService.

func (*CreateServiceOperation) Done

func (op *CreateServiceOperation) Done() bool

func (*CreateServiceOperation) Metadata

Metadata returns metadata associated with the long-running operation. Metadata itself does not contact the server, but Poll does. To get the latest metadata, call this method after a successful call to Poll. If the metadata is not available, the returned metadata and error are both nil.

func (*CreateServiceOperation) Name

func (op *CreateServiceOperation) Name() string

Name returns the name of the long-running operation. The name is assigned by the server and is unique within the service from which the operation is created.

func (*CreateServiceOperation) Poll

Poll fetches the latest state of the long-running operation.

Poll also fetches the latest metadata, which can be retrieved by Metadata.

If Poll fails, the error is returned and op is unmodified. If Poll succeeds and the operation has completed with failure, the error is returned and op.Done will return true. If Poll succeeds and the operation has completed successfully, op.Done will return true, and the response of the operation is returned. If Poll succeeds and the operation has not completed, the returned response and error are both nil.

func (*CreateServiceOperation) Wait

Wait blocks until the long-running operation is completed, returning the response and any errors encountered.

DataprocMetastoreClient

type DataprocMetastoreClient struct {

	// The call options for this service.
	CallOptions *DataprocMetastoreCallOptions

	// LROClient is used internally to handle long-running operations.
	// It is exposed so that its CallOptions can be modified if required.
	// Users should not Close this client.
	LROClient *lroauto.OperationsClient
	// contains filtered or unexported fields
}

DataprocMetastoreClient is a client for interacting with Dataproc Metastore API. Methods, except Close, may be called concurrently. However, fields must not be modified concurrently with method calls.

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}.

func NewDataprocMetastoreClient

func NewDataprocMetastoreClient(ctx context.Context, opts ...option.ClientOption) (*DataprocMetastoreClient, error)

NewDataprocMetastoreClient creates a new dataproc metastore client based on gRPC. The returned client must be Closed when it is done being used to clean up its underlying connections.
