Package com.google.cloud.metastore.v1alpha (2.2.0)

A client to Dataproc Metastore API

The interfaces provided are listed below, along with usage samples.

DataprocMetastoreClient

Service Description: 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}.

Sample for DataprocMetastoreClient:


 try (DataprocMetastoreClient dataprocMetastoreClient = DataprocMetastoreClient.create()) {
   ServiceName name = ServiceName.of("[PROJECT]", "[LOCATION]", "[SERVICE]");
   Service response = dataprocMetastoreClient.getService(name);
 }

DataprocMetastoreClient

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}.

This class provides the ability to make remote calls to the backing service through method calls that map to API methods. Sample code to get started:


 try (DataprocMetastoreClient dataprocMetastoreClient = DataprocMetastoreClient.create()) {
   ServiceName name = ServiceName.of("[PROJECT]", "[LOCATION]", "[SERVICE]");
   Service response = dataprocMetastoreClient.getService(name);
 }

Note: close() needs to be called on the DataprocMetastoreClient object to clean up resources such as threads. In the example above, try-with-resources is used, which automatically calls close().

The surface of this class includes several types of Java methods for each of the API's methods:

A "flattened" method. With this type of method, the fields of the request type have been converted into function parameters. It may be the case that not all fields are available as parameters, and not every API method will have a flattened method entry point.
A "request object" method. This type of method only takes one parameter, a request object, which must be constructed before the call. Not every API method will have a request object method.
A "callable" method. This type of method takes no parameters and returns an immutable API callable object, which can be used to initiate calls to the service.

See the individual methods for example code.

Many parameters require resource names to be formatted in a particular way. To assist with these names, this class includes a format method for each type of name, and additionally a parse method to extract the individual identifiers contained within names that are returned.

This class can be customized by passing in a custom instance of DataprocMetastoreSettings to create(). For example:

To customize credentials:


 DataprocMetastoreSettings dataprocMetastoreSettings =
     DataprocMetastoreSettings.newBuilder()
         .setCredentialsProvider(FixedCredentialsProvider.create(myCredentials))
         .build();
 DataprocMetastoreClient dataprocMetastoreClient =
     DataprocMetastoreClient.create(dataprocMetastoreSettings);

To customize the endpoint:


 DataprocMetastoreSettings dataprocMetastoreSettings =
     DataprocMetastoreSettings.newBuilder().setEndpoint(myEndpoint).build();
 DataprocMetastoreClient dataprocMetastoreClient =
     DataprocMetastoreClient.create(dataprocMetastoreSettings);

DataprocMetastoreGrpc

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:

DataprocMetastoreSettings

Settings class to configure an instance of DataprocMetastoreClient.

The default instance has everything set to sensible defaults:

The default service address (metastore.googleapis.com) and default port (443) are used.
Credentials are acquired automatically through Application Default Credentials.
Retries are configured for idempotent methods but not for non-idempotent methods.

The builder of this class is recursive, so contained classes are themselves builders. When build() is called, the tree of builders is called to create the complete settings object.

For example, to set the total timeout of getService to 30 seconds:


 DataprocMetastoreSettings.Builder dataprocMetastoreSettingsBuilder =
     DataprocMetastoreSettings.newBuilder();
 dataprocMetastoreSettingsBuilder
     .getServiceSettings()
     .setRetrySettings(
         dataprocMetastoreSettingsBuilder
             .getServiceSettings()
             .getRetrySettings()
             .toBuilder()
             .setTotalTimeout(Duration.ofSeconds(30))
