Enclosing class:
BigQueryWriteGrpc
public static final class BigQueryWriteGrpc.BigQueryWriteStub extends io.grpc.stub.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](/bigquery/docs/reference/storage/rpc/google.cloud.bigquery.storage.v1)
   should be used instead of the v1beta2 API for BigQueryWrite operations.

    • createWriteStream

      public void createWriteStream(CreateWriteStreamRequest request, io.grpc.stub.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.

    • appendRows

      public io.grpc.stub.StreamObserver<AppendRowsRequest> appendRows(io.grpc.stub.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.

    • getWriteStream

      public void getWriteStream(GetWriteStreamRequest request, io.grpc.stub.StreamObserver<WriteStream> responseObserver)
       Gets a write stream.

    • finalizeWriteStream

      public void finalizeWriteStream(FinalizeWriteStreamRequest request, io.grpc.stub.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.

    • batchCommitWriteStreams

      public void batchCommitWriteStreams(BatchCommitWriteStreamsRequest request, io.grpc.stub.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.

    • flushRows

      public void flushRows(FlushRowsRequest request, io.grpc.stub.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.
