Class BigQueryWriteClient (2.44.1)

public class BigQueryWriteClient implements BackgroundResource

Service Description: BigQuery Write API.

The Write API can be used to write data to BigQuery.

The google.cloud.bigquery.storage.v1 API should be used instead of the v1beta2 API for BigQueryWrite operations.

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 (BigQueryWriteClient bigQueryWriteClient = BigQueryWriteClient.create()) {
   TableName parent = TableName.of("[PROJECT]", "[DATASET]", "[TABLE]");
   WriteStream writeStream = WriteStream.newBuilder().build();
   WriteStream response = bigQueryWriteClient.createWriteStream(parent, writeStream);
 }

Note: close() needs to be called on the BigQueryWriteClient 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 BigQueryWriteSettings 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
 BigQueryWriteSettings bigQueryWriteSettings =
     BigQueryWriteSettings.newBuilder()
         .setCredentialsProvider(FixedCredentialsProvider.create(myCredentials))
         .build();
 BigQueryWriteClient bigQueryWriteClient = BigQueryWriteClient.create(bigQueryWriteSettings);

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
 BigQueryWriteSettings bigQueryWriteSettings =
     BigQueryWriteSettings.newBuilder().setEndpoint(myEndpoint).build();
 BigQueryWriteClient bigQueryWriteClient = BigQueryWriteClient.create(bigQueryWriteSettings);

`BigQueryWriteClient`

Exceptions
Type	Description
`IOException`

create(BigQueryWriteSettings settings)

public static final BigQueryWriteClient create(BigQueryWriteSettings settings)

Methods

appendRowsCallable()

public final BidiStreamingCallable<AppendRowsRequest,AppendRowsResponse> appendRowsCallable()

Appends data to the given stream.

If offset is specified, the offset is checked against the end of stream. The server returns OUT_OF_RANGE in AppendRowsResponse if an attempt is made to append to an offset beyond the current end of the stream or ALREADY_EXISTS if user provids an offset that has already been written to. User can retry with adjusted offset within the same RPC stream. If offset is not specified, append happens at the end of the stream.

The response contains the offset at which the append happened. Responses are received in the same order in which requests are sent. There will be one response for each successful request. If the offset is not set in response, it means append didn't happen due to some errors. If one request fails, all the subsequent requests will also fail until a success request is made again.

If the stream is of PENDING type, data will only be available for read operations after the stream is committed.

Sample code:


 // 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

flushRows(FlushRowsRequest request)
