Service Description: Service for managing DataStore
configuration.

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:


     // This snippet has been automatically generated and should be regarded as a code template only.
     // It will require modifications to work:
     // - It may require correct/in-range values for request initialization.
     // - It may require specifying regional endpoints when creating the service client as shown in
     // https://cloud.google.com/java/docs/setup#configure_endpoints_for_the_client_library
     try (DataStoreServiceClient dataStoreServiceClient = DataStoreServiceClient.create()) {
       DataStoreName name =
           DataStoreName.ofProjectLocationDataStoreName("[PROJECT]", "[LOCATION]", "[DATA_STORE]");
       DataStore response = dataStoreServiceClient.getDataStore(name);
     }
     
Note: close() needs to be called on the DataStoreServiceClient object to clean up resources
such as threads. In the example above, try-with-resources is used, which automatically calls
close().

| Method | Description | Method Variants |
|---|---|---|
| CreateDataStore | Creates a DataStore. DataStore is for storing Documents. To serve these documents for Search, or Recommendation use case, an Engine needs to be created separately. | Request object method variants only take one parameter, a request object, which must be constructed before the call. - createDataStoreAsync(CreateDataStoreRequest request) Methods that return long-running operations have "Async" method variants that return `OperationFuture`, which is used to track polling of the service. - createDataStoreAsync(CollectionName parent, DataStore dataStore, String dataStoreId) - createDataStoreAsync(String parent, DataStore dataStore, String dataStoreId) Callable method variants take no parameters and return an immutable API callable object, which can be used to initiate calls to the service. - createDataStoreOperationCallable() - createDataStoreCallable() |
| GetDataStore | Gets a DataStore. | Request object method variants only take one parameter, a request object, which must be constructed before the call. - getDataStore(GetDataStoreRequest request) "Flattened" method variants have converted the fields of the request object into function parameters to enable multiple ways to call the same method. - getDataStore(DataStoreName name) - getDataStore(String name) Callable method variants take no parameters and return an immutable API callable object, which can be used to initiate calls to the service. - getDataStoreCallable() |
| ListDataStores | Lists all the DataStores associated with the project. | Request object method variants only take one parameter, a request object, which must be constructed before the call. - listDataStores(ListDataStoresRequest request) "Flattened" method variants have converted the fields of the request object into function parameters to enable multiple ways to call the same method. - listDataStores(CollectionName parent) - listDataStores(String parent) Callable method variants take no parameters and return an immutable API callable object, which can be used to initiate calls to the service. - listDataStoresPagedCallable() - listDataStoresCallable() |
| DeleteDataStore | Deletes a DataStore. | Request object method variants only take one parameter, a request object, which must be constructed before the call. - deleteDataStoreAsync(DeleteDataStoreRequest request) Methods that return long-running operations have "Async" method variants that return `OperationFuture`, which is used to track polling of the service. - deleteDataStoreAsync(DataStoreName name) - deleteDataStoreAsync(String name) Callable method variants take no parameters and return an immutable API callable object, which can be used to initiate calls to the service. - deleteDataStoreOperationCallable() - deleteDataStoreCallable() |
| UpdateDataStore | Updates a DataStore | Request object method variants only take one parameter, a request object, which must be constructed before the call. - updateDataStore(UpdateDataStoreRequest request) "Flattened" method variants have converted the fields of the request object into function parameters to enable multiple ways to call the same method. - updateDataStore(DataStore dataStore, FieldMask updateMask) Callable method variants take no parameters and return an immutable API callable object, which can be used to initiate calls to the service. - updateDataStoreCallable() |
[Methods]

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 DataStoreServiceSettings to
create(). For example:

To customize credentials:


     // This snippet has been automatically generated and should be regarded as a code template only.
     // It will require modifications to work:
     // - It may require correct/in-range values for request initialization.
     // - It may require specifying regional endpoints when creating the service client as shown in
     // https://cloud.google.com/java/docs/setup#configure_endpoints_for_the_client_library
     DataStoreServiceSettings dataStoreServiceSettings =
         DataStoreServiceSettings.newBuilder()
             .setCredentialsProvider(FixedCredentialsProvider.create(myCredentials))
             .build();
     DataStoreServiceClient dataStoreServiceClient =
         DataStoreServiceClient.create(dataStoreServiceSettings);
     
To customize the endpoint:


     // This snippet has been automatically generated and should be regarded as a code template only.
     // It will require modifications to work:
     // - It may require correct/in-range values for request initialization.
     // - It may require specifying regional endpoints when creating the service client as shown in
     // https://cloud.google.com/java/docs/setup#configure_endpoints_for_the_client_library
     DataStoreServiceSettings dataStoreServiceSettings =
         DataStoreServiceSettings.newBuilder().setEndpoint(myEndpoint).build();
     DataStoreServiceClient dataStoreServiceClient =
         DataStoreServiceClient.create(dataStoreServiceSettings);
     
To use REST (HTTP1.1/JSON) transport (instead of gRPC) for sending and receiving requests over
the wire:


     // This snippet has been automatically generated and should be regarded as a code template only.
     // It will require modifications to work:
     // - It may require correct/in-range values for request initialization.
     // - It may require specifying regional endpoints when creating the service client as shown in
     // https://cloud.google.com/java/docs/setup#configure_endpoints_for_the_client_library
     DataStoreServiceSettings dataStoreServiceSettings =
         DataStoreServiceSettings.newHttpJsonBuilder().build();
     DataStoreServiceClient dataStoreServiceClient =
         DataStoreServiceClient.create(dataStoreServiceSettings);
