getAutodetect()

public Boolean getAutodetect()

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

Returns

Type	Description
`Boolean`

getClustering()

public Clustering getClustering()

Returns the clustering specification for the definition table.

Returns

Type	Description
`Clustering`

getCreateDisposition()

public JobInfo.CreateDisposition getCreateDisposition()

Returns whether the job is allowed to create new tables.

Returns

Type	Description
`JobInfo.CreateDisposition`

getCsvOptions()

public CsvOptions getCsvOptions()

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

Returns

Type	Description

getDatastoreBackupOptions()

public DatastoreBackupOptions getDatastoreBackupOptions()

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

Returns

Type	Description
`DatastoreBackupOptions`

getDecimalTargetTypes()

public List<String> getDecimalTargetTypes()

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.

Returns

Type	Description
`List<String>`

getDestinationEncryptionConfiguration()

public EncryptionConfiguration getDestinationEncryptionConfiguration()

Returns

Type	Description
`EncryptionConfiguration`

getDestinationTable()

public TableId getDestinationTable()

Returns the destination table to load the data into.

Returns

Type	Description
`TableId`

getFormat()

public String getFormat()

Returns the format of the data files.

Returns

Type	Description
`String`

getLabels()

public Map<String,String> getLabels()

Returns

Type	Description
`Map<String,String>`

getMaxBadRecords()

public Integer getMaxBadRecords()

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.

Returns

Type	Description
`Integer`

getSchemaUpdateOptions()

public List<JobInfo.SchemaUpdateOption> getSchemaUpdateOptions()

[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.

Returns

Type	Description
`List<SchemaUpdateOption>`

Returns the time partitioning specification defined for the destination table.

Returns

Type	Description
`TimePartitioning`
