Instance Method Details

#append_rows(request, options = nil) {|response, operation| ... } ⇒ ::Enumerable<::Google::Cloud::Bigquery::Storage::V1::AppendRowsResponse>

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.

Examples:

Basic example

require "google/cloud/bigquery/storage/v1"

# Create a client object. The client can be reused for multiple calls.
client = Google::Cloud::Bigquery::Storage::V1::BigQueryWrite::Client.new

# Create an input stream.
input = Gapic::StreamInput.new

# Call the append_rows method to start streaming.
output = client.append_rows input

# Send requests on the stream. For each request object, set fields by
# passing keyword arguments. Be sure to close the stream when done.
input << Google::Cloud::Bigquery::Storage::V1::AppendRowsRequest.new
input << Google::Cloud::Bigquery::Storage::V1::AppendRowsRequest.new
input.close

# The returned object is a streamed enumerable yielding elements of type
# ::Google::Cloud::Bigquery::Storage::V1::AppendRowsResponse
output.each do |current_response|
  p current_response
end

Parameters:

Yields:

  • (response, operation) —

    Access the result along with the RPC operation

Yield Parameters:

Returns:

Raises:

  • (::Google::Cloud::Error) —

    if the RPC is aborted.

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.

Examples:

Basic example

#create_write_stream(request, options = nil) ⇒ ::Google::Cloud::Bigquery::Storage::V1::WriteStream #create_write_stream(parent: nil, write_stream: nil) ⇒ ::Google::Cloud::Bigquery::Storage::V1::WriteStream

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

Examples:

Basic example

require "google/cloud/bigquery/storage/v1"

# Create a client object. The client can be reused for multiple calls.
client = Google::Cloud::Bigquery::Storage::V1::BigQueryWrite::Client.new

# Create a request. To set request fields, pass in keyword arguments.
request = Google::Cloud::Bigquery::Storage::V1::CreateWriteStreamRequest.new

# Call the create_write_stream method.
result = client.create_write_stream request

# The returned object is of type Google::Cloud::Bigquery::Storage::V1::WriteStream.
p result

    • options (::Gapic::CallOptions, ::Hash) (defaults to: nil) —

      Overrides the default settings for this call, e.g, timeout, retries, etc. Optional.

  • #create_write_stream(parent: nil, write_stream: nil) ⇒ ::Google::Cloud::Bigquery::Storage::V1::WriteStream

    Pass arguments to create_write_stream via keyword arguments. Note that at least one keyword argument is required. To specify no parameters, or to keep all the default parameter values, pass an empty Hash as a request object (see above).

    Parameters:

    • parent (::String) (defaults to: nil) —

      Required. Reference to the table to which the stream belongs, in the format of projects/{project}/datasets/{dataset}/tables/{table}.

    • write_stream (::Google::Cloud::Bigquery::Storage::V1::WriteStream, ::Hash) (defaults to: nil) —

      Required. Stream to be created.

Yields:

  • (response, operation) —

    Access the result along with the RPC operation

Yield Parameters:

Returns:

Raises:

  • (::Google::Cloud::Error) —

    if the RPC is aborted.

#flush_rows(request, options = nil) ⇒ ::Google::Cloud::Bigquery::Storage::V1::FlushRowsResponse #flush_rows(write_stream: nil, offset: nil) ⇒ ::Google::Cloud::Bigquery::Storage::V1::FlushRowsResponse

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.

Examples:

Basic example

require "google/cloud/bigquery/storage/v1"

# Create a client object. The client can be reused for multiple calls.
client = Google::Cloud::Bigquery::Storage::V1::BigQueryWrite::Client.new

# Create a request. To set request fields, pass in keyword arguments.
request = Google::Cloud::Bigquery::Storage::V1::FlushRowsRequest.new

# Call the flush_rows method.
result = client.flush_rows request

# The returned object is of type Google::Cloud::Bigquery::Storage::V1::FlushRowsResponse.
p result

Overloads:

  • #flush_rows(request, options = nil) ⇒ ::Google::Cloud::Bigquery::Storage::V1::FlushRowsResponse

    Pass arguments to flush_rows via a request object, either of type FlushRowsRequest or an equivalent Hash.

    Parameters:

    • request (::Google::Cloud::Bigquery::Storage::V1::FlushRowsRequest, ::Hash) —

      A request object representing the call parameters. Required. To specify no parameters, or to keep all the default parameter values, pass an empty Hash.

    • options (::Gapic::CallOptions, ::Hash) (defaults to: nil) —

      Overrides the default settings for this call, e.g, timeout, retries, etc. Optional.

  • #flush_rows(write_stream: nil, offset: nil) ⇒ ::Google::Cloud::Bigquery::Storage::V1::FlushRowsResponse

    Pass arguments to flush_rows via keyword arguments. Note that at least one keyword argument is required. To specify no parameters, or to keep all the default parameter values, pass an empty Hash as a request object (see above).

    Parameters:

    • write_stream (::String) (defaults to: nil) —

      Required. The stream that is the target of the flush operation.

    • offset (::Google::Protobuf::Int64Value, ::Hash) (defaults to: nil) —

      Ending offset of the flush operation. Rows before this offset(including this offset) will be flushed.

Yields:

  • (response, operation) —

    Access the result along with the RPC operation

Yield Parameters:

Returns:

Raises:

  • (::Google::Cloud::Error) —

    if the RPC is aborted.
