LoadConfiguration (BigQuery Parent 2.29.0 API)

All Known Implementing Classes:

LoadJobConfiguration, WriteChannelConfiguration
```
public interface LoadConfiguration
```
Common interface for a load configuration. A load configuration (WriteChannelConfiguration) can be used to load data into a table with a WriteChannel (BigQuery.writer(WriteChannelConfiguration)). A load configuration (LoadJobConfiguration) can also be used to create a load job (JobInfo.of(JobConfiguration)).

- Method Detail
  - getDestinationTable
```
TableId getDestinationTable()
```
    Returns the destination table to load the data into.
  - getDestinationEncryptionConfiguration
```
EncryptionConfiguration getDestinationEncryptionConfiguration()
```
  - getCreateDisposition
```
JobInfo.CreateDisposition getCreateDisposition()
```
    Returns whether the job is allowed to create new tables.
    
    See Also:
    
    Create Disposition
  - getWriteDisposition
```
JobInfo.WriteDisposition getWriteDisposition()
```
    Returns the action that should occur if the destination table already exists.
    
    See Also:
    
    Write Disposition
  - getNullMarker
```
String getNullMarker()
```
    Returns the string that represents a null value in a CSV file.
    
    See Also:
    
    Null Marker
  - getCsvOptions
```
CsvOptions getCsvOptions()
```
    Returns additional properties used to parse CSV data (used when getFormat() is set to CSV). Returns null if not set.
  - getMaxBadRecords
```
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.
  - getSchema
```
Schema getSchema()
```
    Returns the schema for the destination table, if set. Returns null otherwise.
  - getFormat
```
String getFormat()
```
    Returns the format of the data files.
  - ignoreUnknownValues
```
Boolean ignoreUnknownValues()
```
    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.
  - getDatastoreBackupOptions
```
DatastoreBackupOptions getDatastoreBackupOptions()
```
    Returns additional options used to load from a Cloud datastore backup.
  - getSchemaUpdateOptions
```
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.
  - getAutodetect
```
Boolean getAutodetect()
```
    [Experimental] Returns whether automatic inference of the options and schema for CSV and JSON sources is set.
  - getTimePartitioning
```
TimePartitioning getTimePartitioning()
```
    Returns the time partitioning specification defined for the destination table.
  - getClustering
```
Clustering getClustering()
```
    Returns the clustering specification for the definition table.
  - getUseAvroLogicalTypes
```
Boolean getUseAvroLogicalTypes()
```
    Returns True/False. Indicates whether the logical type is interpreted.
  - getDecimalTargetTypes
```
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.
  - toBuilder
```
LoadConfiguration.Builder toBuilder()
```
    Returns a builder for the load configuration object.
