Class v1.BigQueryWriteClient (3.1.1)

BigQuery Write API.

The Write API can be used to write data to BigQuery.

For supplementary information about the Write API, see: https://cloud.google.com/bigquery/docs/write-api v1

Package

@google-cloud/bigquery-storage

Constructors

(constructor)(opts, gaxInstance)

constructor(opts?: ClientOptions, gaxInstance?: typeof gax | typeof gax.fallback);

Construct an instance of BigQueryWriteClient.

Parameters
NameDescription
opts ClientOptions
gaxInstance typeof gax | typeof gax.fallback

: loaded instance of google-gax. Useful if you need to avoid loading the default gRPC version and want to use the fallback HTTP implementation. Load only fallback version and pass it to the constructor: ``` const gax = require('google-gax/build/src/fallback'); // avoids loading google-gax with gRPC const client = new BigQueryWriteClient({fallback: 'rest'}, gax); ```

Properties

Methods

appendRows(options)

appendRows(options?: CallOptions): gax.CancellableStream;

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.

Note: For users coding against the gRPC api directly, it may be necessary to supply the x-goog-request-params system parameter with write_stream=<full_write_stream_name>.

Parameter

Returns
TypeDescription
gax.CancellableStream

{Stream} An object stream which is both readable and writable. It accepts objects representing [AppendRowsRequest] for write() method, and will emit objects representing [AppendRowsResponse] on 'data' event asynchronously. Please see the [documentation](https://github.com/googleapis/gax-nodejs/blob/master/client-libraries.md#bi-directional-streaming) for more details and examples.

   *  For explicitly created write streams, the format is:

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.

initialize()

initialize(): Promise<{
        [name: string]: Function;

Initialize the client. Performs asynchronous operations (such as authentication) and prepares the client.
