Class v1.BigQueryWriteClient (4.5.0)

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

Constructors

(constructor)(opts, gaxInstance)

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

Construct an instance of BigQueryWriteClient.

Parameters
Name	Description
`opts`	`ClientOptions`
`gaxInstance`	`typeof gax \| typeof 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: true}, gax); ```

Properties

apiEndpoint

get apiEndpoint(): string;

The DNS address for this API service.

apiEndpoint

static get apiEndpoint(): string;

        [name: string]: Function;
    }>;

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.

Parameter
Name	Description
`options`	`CallOptions` Call options. See CallOptions for more details.

Returns
Type	Description
`gax.CancellableStream`	{Stream} An object stream which is both readable and writable. It accepts objects representing for write() method, and will emit objects representing on 'data' event asynchronously. Please see the documentation for more details and examples.

  /**
   *  Required. The write_stream identifies the append operation. It must be
   *  provided in the following scenarios:
   *  * In the first request to an AppendRows connection.
   *  * In all subsequent requests to an AppendRows connection, if you use the
   *  same connection to write to multiple tables or change the input schema for
   *  default streams.
   *  For explicitly created write streams, the format is:
   *  * `projects/{project}/datasets/{dataset}/tables/{table}/streams/{id}`
   *  For the special default stream, the format is:
   *  * `projects/{project}/datasets/{dataset}/tables/{table}/streams/_default`.
   *  An example of a possible sequence of requests with write_stream fields
   *  within a single connection:
   *  * r1: {write_stream: stream_name_1}
   *  * r2: {write_stream: /*omit* /}
   *  * r3: {write_stream: /*omit* /}
   *  * r4: {write_stream: stream_name_2}
   *  * r5: {write_stream: stream_name_2}
   *  The destination changed in request_4, so the write_stream field must be
   *  populated in all subsequent requests in this stream.

   *  If present, the write is only performed if the next append offset is same

   *  A map to indicate how to interpret missing value for some fields. Missing
   *  values are fields present in user schema but missing in rows. The key is
   *  the field name. The value is the interpretation of missing values for the
   *  field.
   *  For example, a map {'foo': NULL_VALUE, 'bar': DEFAULT_VALUE} means all
   *  missing values in field foo are interpreted as NULL, all missing values in
   *  field bar are interpreted as the default value of field bar in table
   *  schema.
   *  If a field is not in this map and has missing values, the missing values
   *  in this field are interpreted as NULL.
   *  This field only applies to the current request, it won't affect other
   *  requests on the connection.
   *  Currently, field name can only be top-level column name, can't be a struct
   *  field path like 'foo.bar'.

   *  subsequent `AppendRowsRequest` sets it to a different value.
   *  `missing_value_interpretation` can override
   *  `default_missing_value_interpretation`. For example, if you want to write
   *  `NULL` instead of using default values for some columns, you can set
   *  `default_missing_value_interpretation` to `DEFAULT_VALUE` and at the same
