Methods

AppendRows(CallSettings, BidirectionalStreamingSettings)

public virtual BigQueryWriteClient.AppendRowsStream AppendRows(CallSettings callSettings = null, BidirectionalStreamingSettings streamingSettings = null)

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.

Parameters
Name	Description
callSettings	CallSettings If not null, applies overrides to this RPC call.
streamingSettings	BidirectionalStreamingSettings If not null, applies streaming overrides to this RPC call.

Returns
Type	Description
BigQueryWriteClient.AppendRowsStream	The client-server stream.

Example

// Create client
BigQueryWriteClient bigQueryWriteClient = BigQueryWriteClient.Create();
// Initialize streaming call, retrieving the stream object
BigQueryWriteClient.AppendRowsStream response = bigQueryWriteClient.AppendRows();

// Sending requests and retrieving responses can be arbitrarily interleaved
// Exact sequence will depend on client/server behavior

// Create task to do something with responses from server
Task responseHandlerTask = Task.Run(async () =>
{
    // Note that C# 8 code can use await foreach
    AsyncResponseStream<AppendRowsResponse> responseStream = response.GetResponseStream();
    while (await responseStream.MoveNextAsync())
    {
        AppendRowsResponse responseItem = responseStream.Current;
        // Do something with streamed response
    }
    // The response stream has completed
});

// Send requests to the server
bool done = false;
while (!done)
{
    // Initialize a request
    AppendRowsRequest request = new AppendRowsRequest
    {
        WriteStreamAsWriteStreamName = WriteStreamName.FromProjectDatasetTableStream("[PROJECT]", "[DATASET]", "[TABLE]", "[STREAM]"),
        Offset = 0L,
        ProtoRows = new AppendRowsRequest.Types.ProtoData(),
        TraceId = "",
        MissingValueInterpretations =
        {
            {
                "",
                AppendRowsRequest.Types.MissingValueInterpretation.Unspecified
            },
        },
    };
    // Stream a request to the server
    await response.WriteAsync(request);
    // Set "done" to true when sending requests is complete
}

// Complete writing requests to the stream
await response.WriteCompleteAsync();
// Await the response handler
// This will complete once all server responses have been processed
await responseHandlerTask;
