/**
 * Service Description: BigQuery Write API.
 *
 * <p>The Write API can be used to write data to BigQuery.
 *
 * <p>For supplementary information about the Write API, see:
 * https://cloud.google.com/bigquery/docs/write-api
 *
 * <p>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:
 *
 * <pre>{@code
 * try (BigQueryWriteClient bigQueryWriteClient = BigQueryWriteClient.create()) {
 *   TableName parent = TableName.of("[PROJECT]", "[DATASET]", "[TABLE]");
 *   WriteStream writeStream = WriteStream.newBuilder().build();
 *   WriteStream response = bigQueryWriteClient.createWriteStream(parent, writeStream);
 * }
 * }</pre>
 *
 * <p>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().
 *
 * <p>The surface of this class includes several types of Java methods for each of the API's
 * methods:
 *
 * <ol>
 *   <li>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.
 *   <li>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.
 *   <li>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.
 * </ol>
 *
 * <p>See the individual methods for example code.
 *
 * <p>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.
 *
 * <p>This class can be customized by passing in a custom instance of BigQueryWriteSettings to
 * create(). For example:
 *
 * <p>To customize credentials:
 *
 * <pre>{@code
 * BigQueryWriteSettings bigQueryWriteSettings =
 *     BigQueryWriteSettings.newBuilder()
 *         .setCredentialsProvider(FixedCredentialsProvider.create(myCredentials))
 *         .build();
 * BigQueryWriteClient bigQueryWriteClient = BigQueryWriteClient.create(bigQueryWriteSettings);
 * }</pre>
 *
 * <p>To customize the endpoint:
 *
 * <pre>{@code
 * BigQueryWriteSettings bigQueryWriteSettings =
 *     BigQueryWriteSettings.newBuilder().setEndpoint(myEndpoint).build();
 * BigQueryWriteClient bigQueryWriteClient = BigQueryWriteClient.create(bigQueryWriteSettings);
 * }</pre>
 *
 * <p>Please refer to the GitHub repository's samples for more quickstart code snippets.

   * Appends data to the given stream.
   *
   * <p>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.
   *
   * <p>The response contains an optional offset at which the append happened. No offset information
   * will be returned for appends to a default stream.
   *
   * <p>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.
   *
   * <p>The specifics of when successfully appended data is made visible to the table are governed
   * by the type of stream:
   *
   * <ul>
   *   <li>For COMMITTED streams (which includes the default stream), data is visible immediately
   *       upon successful append.
   * </ul>
   *
   * <ul>
   *   <li>For BUFFERED streams, data is made visible via a subsequent `FlushRows` rpc which
   *       advances a cursor to a newer offset in the stream.
   * </ul>
   *
   * <ul>
   *   <li>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.
   * </ul>
   *
   * <p>Note: For users coding against the gRPC api directly, it may be necessary to supply the
   * x-goog-request-params system parameter with `write_stream=&lt;full_write_stream_name&gt;`.
