Method Details

setDestinationTable

public WriteChannelConfiguration.Builder setDestinationTable(TableId destinationTable)

Description copied from interface: LoadConfiguration.Builder

Sets the destination table to load the data into.

Specified by:

setDestinationTable in interface LoadConfiguration.Builder

setDestinationEncryptionConfiguration

public LoadConfiguration.Builder setDestinationEncryptionConfiguration(EncryptionConfiguration encryptionConfiguration)

Specified by:

setDestinationEncryptionConfiguration in interface LoadConfiguration.Builder

setCreateDisposition

public WriteChannelConfiguration.Builder setCreateDisposition(JobInfo.CreateDisposition createDisposition)

Description copied from interface: LoadConfiguration.Builder

Sets whether the job is allowed to create new tables.

Specified by:

setCreateDisposition in interface LoadConfiguration.Builder

See Also:

• Create Disposition

setWriteDisposition

public WriteChannelConfiguration.Builder setWriteDisposition(JobInfo.WriteDisposition writeDisposition)

Description copied from interface: LoadConfiguration.Builder

Sets the action that should occur if the destination table already exists.

Specified by:

setWriteDisposition in interface LoadConfiguration.Builder

See Also:

• Write Disposition

setFormatOptions

public WriteChannelConfiguration.Builder setFormatOptions(FormatOptions formatOptions)

Description copied from interface: LoadConfiguration.Builder

Sets the source format, and possibly some parsing options, of the external data. Supported formats are CSV, NEWLINE_DELIMITED_JSON and DATASTORE_BACKUP. If not specified, CSV format is assumed.

Source Format

Specified by:

setFormatOptions in interface LoadConfiguration.Builder

setNullMarker

public WriteChannelConfiguration.Builder setNullMarker(String nullMarker)

Description copied from interface: LoadConfiguration.Builder

Sets the string that represents a null value in a CSV file. For example, if you specify "\N", BigQuery interprets "\N" as a null value when loading a CSV file. The default value is the empty string. If you set this property to a custom value, BigQuery throws an error if an empty string is present for all data types except for STRING and BYTE. For STRING and BYTE columns, BigQuery interprets the empty string as an empty value.

Specified by:

setNullMarker in interface LoadConfiguration.Builder

setMaxBadRecords

public WriteChannelConfiguration.Builder setMaxBadRecords(Integer maxBadRecords)

Description copied from interface: LoadConfiguration.Builder

Sets the maximum number of bad records that BigQuery can ignore when running the job. If the number of bad records exceeds this value, an invalid error is returned in the job result. By default no bad record is ignored.

Specified by:

setMaxBadRecords in interface LoadConfiguration.Builder

setSchema

public WriteChannelConfiguration.Builder setSchema(Schema schema)

Description copied from interface: LoadConfiguration.Builder

Sets the schema for the destination table. The schema can be omitted if the destination table already exists, or if you're loading data from a Google Cloud Datastore backup (i.e. DATASTORE_BACKUP format option).

Specified by:

setSchema in interface LoadConfiguration.Builder

setIgnoreUnknownValues

public WriteChannelConfiguration.Builder setIgnoreUnknownValues(Boolean ignoreUnknownValues)

Description copied from interface: LoadConfiguration.Builder

Sets whether BigQuery should allow extra values that are not represented in the table schema. If true, the extra values are ignored. If false, records with extra columns are treated as bad records, and if there are too many bad records, an invalid error is returned in the job result. By default unknown values are not allowed.

Specified by:

setIgnoreUnknownValues in interface LoadConfiguration.Builder

setSchemaUpdateOptions

public WriteChannelConfiguration.Builder setSchemaUpdateOptions(List<JobInfo.SchemaUpdateOption> schemaUpdateOptions)

Description copied from interface: LoadConfiguration.Builder

[Experimental] Sets options allowing the schema of the destination table to be updated as a side effect of the load job. Schema update options are supported in two cases: when writeDisposition is WRITE_APPEND; when writeDisposition is WRITE_TRUNCATE and the destination table is a partition of a table, specified by partition decorators. For normal tables, WRITE_TRUNCATE will always overwrite the schema.

Specified by:

setSchemaUpdateOptions in interface LoadConfiguration.Builder

setAutodetect

public WriteChannelConfiguration.Builder setAutodetect(Boolean autodetect)

Description copied from interface: LoadConfiguration.Builder

[Experimental] Sets automatic inference of the options and schema for CSV and JSON sources.

Specified by:

setAutodetect in interface LoadConfiguration.Builder

setTimePartitioning

public WriteChannelConfiguration.Builder setTimePartitioning(TimePartitioning timePartitioning)

Description copied from interface: LoadConfiguration.Builder

Sets the time partitioning specification for the destination table.

Specified by:

setTimePartitioning in interface LoadConfiguration.Builder

setClustering

public WriteChannelConfiguration.Builder setClustering(Clustering clustering)

Description copied from interface: LoadConfiguration.Builder

Sets the clustering specification for the destination table.

Specified by:

setClustering in interface LoadConfiguration.Builder

setUseAvroLogicalTypes

public WriteChannelConfiguration.Builder setUseAvroLogicalTypes(Boolean useAvroLogicalTypes)

Description copied from interface: LoadConfiguration.Builder

If FormatOptions is set to AVRO, you can interpret logical types into their corresponding types (such as TIMESTAMP) instead of only using their raw types (such as INTEGER). The value may be null.

Specified by:

setUseAvroLogicalTypes in interface LoadConfiguration.Builder

setLabels

public WriteChannelConfiguration.Builder setLabels(Map<String,String> labels)

setDecimalTargetTypes

public WriteChannelConfiguration.Builder setDecimalTargetTypes(List<String> decimalTargetTypes)

Description copied from interface: LoadConfiguration.Builder

Defines the list of possible SQL data types to which the source decimal values are converted. This list and the precision and the scale parameters of the decimal field determine the target type. In the order of NUMERIC, BIGNUMERIC, and STRING, a type is picked if it is in the specified list and if it supports the precision and the scale. STRING supports all precision and scale values.

Specified by:

setDecimalTargetTypes in interface LoadConfiguration.Builder

Parameters:

decimalTargetTypes - decimalTargetType or null for none

setConnectionProperties

public WriteChannelConfiguration.Builder setConnectionProperties(List<ConnectionProperty> connectionProperties)

setCreateSession

public WriteChannelConfiguration.Builder setCreateSession(Boolean createSession)

build

public WriteChannelConfiguration build()

Specified by:
