Methods

appendRows(StreamObserver<AppendRowsResponse> responseObserver)

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)

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>`

bindService()

public final ServerServiceDefinition bindService()

Returns

Type	Description
io.grpc.ServerServiceDefinition

createWriteStream(CreateWriteStreamRequest request, StreamObserver<WriteStream> responseObserver)

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)

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)

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)

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

Gets a write stream.

Parameters

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