Class BigQueryWriteClient (3.4.0)

public class BigQueryWriteClient implements BackgroundResource

Service Description: BigQuery Write API.

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

For supplementary information about the Write API, see: https://cloud.google.com/bigquery/docs/write-api

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().

Methods
Method	Description	Method Variants
CreateWriteStream	Creates a write stream to the given table. Additionally, every table has a special stream named '_default' to which data can be written. This stream doesn't need to be created using CreateWriteStream. It is a stream that can be used simultaneously by any number of clients. Data written to this stream is considered committed as soon as an acknowledgement is received.	Request object method variants only take one parameter, a request object, which must be constructed before the call. createWriteStream(CreateWriteStreamRequest request) "Flattened" method variants have converted the fields of the request object into function parameters to enable multiple ways to call the same method. createWriteStream(TableName parent, WriteStream writeStream) createWriteStream(String parent, WriteStream writeStream) Callable method variants take no parameters and return an immutable API callable object, which can be used to initiate calls to the service. createWriteStreamCallable()
AppendRows	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 provides an `offset` that has already been written to. User can retry with adjusted offset within the same RPC connection. If `offset` is not specified, append happens at the end of the stream. The response contains an optional offset at which the append happened. No offset information will be returned for appends to a default stream. Responses are received in the same order in which requests are sent. There will be one response for each successful inserted request. Responses may optionally embed error information if the originating AppendRequest was not successfully processed. The specifics of when successfully appended data is made visible to the table are governed by the type of stream: For COMMITTED streams (which includes the default stream), data is visible immediately upon successful append. For BUFFERED streams, data is made visible via a subsequent `FlushRows` rpc which advances a cursor to a newer offset in the stream. For PENDING streams, data is not made visible until the stream itself is finalized (via the `FinalizeWriteStream` rpc), and the stream is explicitly committed via the `BatchCommitWriteStreams` rpc.	Callable method variants take no parameters and return an immutable API callable object, which can be used to initiate calls to the service. appendRowsCallable()
GetWriteStream	Gets information about a write stream.	Request object method variants only take one parameter, a request object, which must be constructed before the call. getWriteStream(GetWriteStreamRequest request) "Flattened" method variants have converted the fields of the request object into function parameters to enable multiple ways to call the same method. getWriteStream(WriteStreamName name) getWriteStream(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. getWriteStreamCallable()
FinalizeWriteStream	Finalize a write stream so that no new data can be appended to the stream. Finalize is not supported on the '_default' stream.	Request object method variants only take one parameter, a request object, which must be constructed before the call. finalizeWriteStream(FinalizeWriteStreamRequest request) "Flattened" method variants have converted the fields of the request object into function parameters to enable multiple ways to call the same method. finalizeWriteStream(WriteStreamName name) finalizeWriteStream(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. finalizeWriteStreamCallable()
BatchCommitWriteStreams	Atomically commits a group of `PENDING` streams that belong to the same `parent` table. Streams must be finalized before commit and cannot be committed multiple times. Once a stream is committed, data in the stream becomes available for read operations.	Request object method variants only take one parameter, a request object, which must be constructed before the call. batchCommitWriteStreams(BatchCommitWriteStreamsRequest request) "Flattened" method variants have converted the fields of the request object into function parameters to enable multiple ways to call the same method. batchCommitWriteStreams(TableName parent) batchCommitWriteStreams(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. batchCommitWriteStreamsCallable()
FlushRows	Flushes rows to a BUFFERED stream. If users are appending rows to BUFFERED stream, flush operation is required in order for the rows to become available for reading. A Flush operation flushes up to any previously flushed offset in a BUFFERED stream, to the offset specified in the request. Flush is not supported on the _default stream, since it is not BUFFERED.	Request object method variants only take one parameter, a request object, which must be constructed before the call. flushRows(FlushRowsRequest request) "Flattened" method variants have converted the fields of the request object into function parameters to enable multiple ways to call the same method. flushRows(WriteStreamName writeStream) flushRows(String writeStream) Callable method variants take no parameters and return an immutable API callable object, which can be used to initiate calls to the service. flushRowsCallable()

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);

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 provides an offset that has already been written to. User can retry with adjusted offset within the same RPC connection. If offset is not specified, append happens at the end of the stream.

The response contains an optional offset at which the append happened. No offset information will be returned for appends to a default stream.

Responses are received in the same order in which requests are sent. There will be one response for each successful inserted request. Responses may optionally embed error information if the originating AppendRequest was not successfully processed.

The specifics of when successfully appended data is made visible to the table are governed by the type of stream:

For COMMITTED streams (which includes the default stream), data is visible immediately upon successful append.

For BUFFERED streams, data is made visible via a subsequent FlushRows rpc which advances a cursor to a newer offset in the stream.

For PENDING streams, data is not made visible until the stream itself is finalized (via the FinalizeWriteStream rpc), and the stream is explicitly committed via the BatchCommitWriteStreams rpc.
