Class BigQueryWriteGrpc.BigQueryWriteStub (3.6.0)

public static final class BigQueryWriteGrpc.BigQueryWriteStub extends AbstractAsyncStub<BigQueryWriteGrpc.BigQueryWriteStub>

A stub to allow clients to do asynchronous rpc calls to service BigQueryWrite.

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.

Methods

appendRows(StreamObserver<AppendRowsResponse> responseObserver) (deprecated)

public StreamObserver<AppendRowsRequest> appendRows(StreamObserver<AppendRowsResponse> responseObserver)

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.

Parameter
Name Description
responseObserver io.grpc.stub.StreamObserver<AppendRowsResponse>
Returns
Type Description
io.grpc.stub.StreamObserver<AppendRowsRequest>

batchCommitWriteStreams(BatchCommitWriteStreamsRequest request, StreamObserver<BatchCommitWriteStreamsResponse> responseObserver) (deprecated)

public void batchCommitWriteStreams(BatchCommitWriteStreamsRequest request, StreamObserver<BatchCommitWriteStreamsResponse> responseObserver)

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.

Parameters
Name Description
request BatchCommitWriteStreamsRequest
responseObserver io.grpc.stub.StreamObserver<BatchCommitWriteStreamsResponse>

build(Channel channel, CallOptions callOptions) (deprecated)

protected BigQueryWriteGrpc.BigQueryWriteStub build(Channel channel, CallOptions callOptions)
Parameters
Name Description
channel io.grpc.Channel
callOptions io.grpc.CallOptions
Returns
Type Description
BigQueryWriteGrpc.BigQueryWriteStub
Overrides
io.grpc.stub.AbstractStub.build(io.grpc.Channel,io.grpc.CallOptions)

createWriteStream(CreateWriteStreamRequest request, StreamObserver<WriteStream> responseObserver) (deprecated)

public void createWriteStream(CreateWriteStreamRequest request, StreamObserver<WriteStream> responseObserver)

Creates a write stream to the given table. Additionally, every table has a special COMMITTED 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.

Parameters
Name Description
request CreateWriteStreamRequest
responseObserver io.grpc.stub.StreamObserver<WriteStream>

finalizeWriteStream(FinalizeWriteStreamRequest request, StreamObserver<FinalizeWriteStreamResponse> responseObserver) (deprecated)

public void finalizeWriteStream(FinalizeWriteStreamRequest request, StreamObserver<FinalizeWriteStreamResponse> responseObserver)

Finalize a write stream so that no new data can be appended to the stream. Finalize is not supported on the '_default' stream.

Parameters
Name Description
request FinalizeWriteStreamRequest
responseObserver io.grpc.stub.StreamObserver<FinalizeWriteStreamResponse>

flushRows(FlushRowsRequest request, StreamObserver<FlushRowsResponse> responseObserver) (deprecated)

public void flushRows(FlushRowsRequest request, StreamObserver<FlushRowsResponse> responseObserver)

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.

Parameters
Name Description
request FlushRowsRequest
responseObserver io.grpc.stub.StreamObserver<FlushRowsResponse>

getWriteStream(GetWriteStreamRequest request, StreamObserver<WriteStream> responseObserver) (deprecated)

public void getWriteStream(GetWriteStreamRequest request, StreamObserver<WriteStream> responseObserver)

Gets a write stream.

Parameters
Name Description
request GetWriteStreamRequest
responseObserver io.grpc.stub.StreamObserver<WriteStream>
