Method Details

getDestinationTable

public TableId getDestinationTable()

Description copied from interface: LoadConfiguration

Returns the destination table to load the data into.

Specified by:

getDestinationTable in interface LoadConfiguration

getDestinationEncryptionConfiguration

public EncryptionConfiguration getDestinationEncryptionConfiguration()

Specified by:

getDestinationEncryptionConfiguration in interface LoadConfiguration

getCreateDisposition

public JobInfo.CreateDisposition getCreateDisposition()

Description copied from interface: LoadConfiguration

Returns whether the job is allowed to create new tables.

Specified by:

getCreateDisposition in interface LoadConfiguration

See Also:

• Create Disposition

getWriteDisposition

public JobInfo.WriteDisposition getWriteDisposition()

Description copied from interface: LoadConfiguration

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

Specified by:

getWriteDisposition in interface LoadConfiguration

See Also:

• Write Disposition

getNullMarker

public String getNullMarker()

Description copied from interface: LoadConfiguration

Returns the string that represents a null value in a CSV file.

Specified by:

getNullMarker in interface LoadConfiguration

See Also:

• Null Marker

getCsvOptions

public CsvOptions getCsvOptions()

Description copied from interface: LoadConfiguration

Returns additional properties used to parse CSV data (used when LoadConfiguration.getFormat() is set to CSV). Returns null if not set.

Specified by:

getCsvOptions in interface LoadConfiguration

getMaxBadRecords

public Integer getMaxBadRecords()

Description copied from interface: LoadConfiguration

Returns 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:

getMaxBadRecords in interface LoadConfiguration

getSchema

public Schema getSchema()

Description copied from interface: LoadConfiguration

Returns the schema for the destination table, if set. Returns null otherwise.

Specified by:

getSchema in interface LoadConfiguration

getFormat

public String getFormat()

Description copied from interface: LoadConfiguration

Returns the format of the data files.

Specified by:

getFormat in interface LoadConfiguration

ignoreUnknownValues

public Boolean ignoreUnknownValues()

Description copied from interface: LoadConfiguration

Returns whether BigQuery should allow extra values that are not represented in the table schema. If true, the extra values are ignored. If true, 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:

ignoreUnknownValues in interface LoadConfiguration

getDatastoreBackupOptions

public DatastoreBackupOptions getDatastoreBackupOptions()

Description copied from interface: LoadConfiguration

Returns additional options used to load from a Cloud datastore backup.

Specified by:

getDatastoreBackupOptions in interface LoadConfiguration

getSchemaUpdateOptions

public List<JobInfo.SchemaUpdateOption> getSchemaUpdateOptions()

Description copied from interface: LoadConfiguration

[Experimental] Returns 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:

getSchemaUpdateOptions in interface LoadConfiguration

getAutodetect

public Boolean getAutodetect()

Description copied from interface: LoadConfiguration

[Experimental] Returns whether automatic inference of the options and schema for CSV and JSON sources is set.

Specified by:

getAutodetect in interface LoadConfiguration

getTimePartitioning

public TimePartitioning getTimePartitioning()

Description copied from interface: LoadConfiguration

Returns the time partitioning specification defined for the destination table.

Specified by:

getTimePartitioning in interface LoadConfiguration

getClustering

public Clustering getClustering()

Description copied from interface: LoadConfiguration

Returns the clustering specification for the definition table.

Specified by:

getClustering in interface LoadConfiguration

getUseAvroLogicalTypes

public Boolean getUseAvroLogicalTypes()

Description copied from interface: LoadConfiguration

Returns True/False. Indicates whether the logical type is interpreted.

Specified by:

getUseAvroLogicalTypes in interface LoadConfiguration

getLabels

public Map<String,String> getLabels()

getDecimalTargetTypes

public List<String> getDecimalTargetTypes()

Description copied from interface: LoadConfiguration

Returns 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:

getDecimalTargetTypes in interface LoadConfiguration

getConnectionProperties

public List<ConnectionProperty> getConnectionProperties()

getCreateSession

public Boolean getCreateSession()

toBuilder

public WriteChannelConfiguration.Builder toBuilder()

Description copied from interface: LoadConfiguration

Returns a builder for the load configuration object.

Specified by:

toBuilder in interface LoadConfiguration
