Configures and manages metastore services. Metastore services are fully managed, highly available, autoscaled, autohealing, 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}. v1alpha

Package

@google-cloud/dataproc-metastore

Constructors

(constructor)(opts, gaxInstance)

constructor(opts?: ClientOptions, gaxInstance?: typeof gax | typeof gax.fallback);

Construct an instance of DataprocMetastoreClient.

Parameters
Name	Description
opts	ClientOptions
gaxInstance	typeof gax | typeof gax.fallback : loaded instance of google-gax. Useful if you need to avoid loading the default gRPC version and want to use the fallback HTTP implementation. Load only fallback version and pass it to the constructor: ``` const gax = require('google-gax/build/src/fallback'); // avoids loading google-gax with gRPC const client = new DataprocMetastoreClient({fallback: 'rest'}, gax); ```

Methods

alterMetadataResourceLocation(request, options)

alterMetadataResourceLocation(request?: protos.google.cloud.metastore.v1alpha.IAlterMetadataResourceLocationRequest, options?: CallOptions): Promise<[
        LROperation<protos.google.cloud.metastore.v1alpha.IAlterMetadataResourceLocationResponse, protos.google.cloud.metastore.v1alpha.IOperationMetadata>,
        protos.google.longrunning.IOperation | undefined,
        {} | undefined
    ]>;

Alter metadata resource location. The metadata resource can be a database, table, or partition. This functionality only updates the parent directory for the respective metadata resource and does not transfer any existing data to the new location.

Parameters
Name	Description
request	protos.google.cloud.metastore.v1alpha.IAlterMetadataResourceLocationRequest The request object that will be sent.
options	CallOptions Call options. See CallOptions for more details.

Returns
Type	Description
Promise<[ LROperation<protos.google.cloud.metastore.v1alpha.IAlterMetadataResourceLocationResponse, protos.google.cloud.metastore.v1alpha.IOperationMetadata>, protos.google.longrunning.IOperation | undefined, {} | undefined ]>	{Promise} - The promise which resolves to an array. The first element of the array is an object representing a long running operation. Its promise() method returns a promise you can await for. Please see the [documentation](https://github.com/googleapis/gax-nodejs/blob/master/client-libraries.md#long-running-operations) for more details and examples.

cancelOperation(request, options, callback)

cancelOperation(request: protos.google.longrunning.CancelOperationRequest, options?: gax.CallOptions | Callback<protos.google.protobuf.Empty, protos.google.longrunning.CancelOperationRequest, {} | undefined | null>, callback?: Callback<protos.google.longrunning.CancelOperationRequest, protos.google.protobuf.Empty, {} | undefined | null>): Promise<protos.google.protobuf.Empty>;

Starts asynchronous cancellation on a long-running operation. The server makes a best effort to cancel the operation, but success is not guaranteed. If the server doesn't support this method, it returns google.rpc.Code.UNIMPLEMENTED. Clients can use or other methods to check whether the cancellation succeeded or whether the operation completed despite cancellation. On successful cancellation, the operation is not deleted; instead, it becomes an operation with an value with a of 1, corresponding to Code.CANCELLED.

Parameters
Name	Description
request	protos.google.longrunning.CancelOperationRequest The request object that will be sent.
options	gax.CallOptions | Callback<protos.google.protobuf.Empty, protos.google.longrunning.CancelOperationRequest, {} | undefined | null> Optional parameters. You can override the default settings for this call, e.g, timeout, retries, paginations, etc. See gax.CallOptions for the details.
callback	Callback<protos.google.longrunning.CancelOperationRequest, protos.google.protobuf.Empty, {} | undefined | null> The function which will be called with the result of the API call. {Promise} - The promise which resolves when API call finishes. The promise has a method named "cancel" which cancels the ongoing API call.

Returns
Type	Description
Promise<protos.google.protobuf.Empty>

Example

const client = longrunning.operationsClient();
await client.cancelOperation({name: ''});

        LROperation<protos.google.cloud.metastore.v1alpha.IMetadataImport, protos.google.cloud.metastore.v1alpha.IOperationMetadata>,
        protos.google.longrunning.IOperation | undefined,
        {} | undefined
    ]>;

Updates a single import. Only the description field of MetadataImport is supported to be updated.

Parameters
Name	Description
request	protos.google.cloud.metastore.v1alpha.IUpdateMetadataImportRequest The request object that will be sent.
options	CallOptions Call options. See CallOptions for more details.

Returns
Type	Description
Promise<[ LROperation<protos.google.cloud.metastore.v1alpha.IMetadataImport, protos.google.cloud.metastore.v1alpha.IOperationMetadata>, protos.google.longrunning.IOperation | undefined, {} | undefined ]>	{Promise} - The promise which resolves to an array. The first element of the array is an object representing a long running operation. Its promise() method returns a promise you can await for. Please see the [documentation](https://github.com/googleapis/gax-nodejs/blob/master/client-libraries.md#long-running-operations) for more details and examples.
