Class BigQueryReadSettings (3.8.0) 

public class BigQueryReadSettings extends ClientSettings<BigQueryReadSettings>

Settings class to configure an instance of BigQueryReadClient.

The default instance has everything set to sensible defaults:

  • The default service address (bigquerystorage.googleapis.com) and default port (443) are used.
  • Credentials are acquired automatically through Application Default Credentials.
  • Retries are configured for idempotent methods but not for non-idempotent methods.

The builder of this class is recursive, so contained classes are themselves builders. When build() is called, the tree of builders is called to create the complete settings object.

For example, to set the total timeout of createReadSession to 30 seconds:

 
 BigQueryReadSettings.Builder BigQueryReadSettingsBuilder =
     BigQueryReadSettings.newBuilder();
 BigQueryReadSettingsBuilder.createReadSessionSettings().getRetrySettings().toBuilder()
     .setTotalTimeout(Duration.ofSeconds(30));
 BigQueryReadSettings BigQueryReadSettings = BigQueryReadSettingsBuilder.build();

Methods

createReadSessionSettings()

public UnaryCallSettings<CreateReadSessionRequest,ReadSession> createReadSessionSettings()

Returns the object with the settings used for calls to createReadSession.

Returns
Type Description
UnaryCallSettings<CreateReadSessionRequest,ReadSession>

getReadRowsRetryAttemptListener()

public BigQueryReadSettings.RetryAttemptListener getReadRowsRetryAttemptListener()
Returns
Type Description
BigQueryReadSettings.RetryAttemptListener

readRowsSettings()

public ServerStreamingCallSettings<ReadRowsRequest,ReadRowsResponse> readRowsSettings()

Returns the object with the settings used for calls to readRows.

Returns
Type Description
ServerStreamingCallSettings<ReadRowsRequest,ReadRowsResponse>

setReadRowsRetryAttemptListener(BigQueryReadSettings.RetryAttemptListener readRowsRetryAttemptListener)

public void setReadRowsRetryAttemptListener(BigQueryReadSettings.RetryAttemptListener readRowsRetryAttemptListener)

If a non null readRowsRetryAttemptListener is provided, client will call onRetryAttempt function before a failed ReadRows request is retried. This can be used as negative feedback mechanism for future decision to split read streams because some retried failures are due to resource exhaustion that increased parallelism only makes it worse.

Parameter
Name Description
readRowsRetryAttemptListener BigQueryReadSettings.RetryAttemptListener

splitReadStreamSettings()

public UnaryCallSettings<SplitReadStreamRequest,SplitReadStreamResponse> splitReadStreamSettings()

Returns the object with the settings used for calls to splitReadStream.

Returns
Type Description
UnaryCallSettings<SplitReadStreamRequest,SplitReadStreamResponse>

toBuilder()

public BigQueryReadSettings.Builder toBuilder()

Returns a builder containing all the values of this settings class.
