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

getDecimalTargetTypes()
public abstract 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.

getDestinationTable()
public abstract TableId getDestinationTable()
Returns the destination table to load the data into.
Returns | |
---|---|
Type | Description |
TableId |
getFormat()
public abstract String getFormat()
Returns the format of the data files.
Returns | |
---|---|
Type | Description |
String |
getMaxBadRecords()
public abstract 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 |
getNullMarker()
public abstract String getNullMarker()
Returns the string that represents a null value in a CSV file. See Also: Null Marker
Returns | |

String |
getSchema()
public abstract Schema getSchema()
Returns the schema for the destination table, if set. Returns null
otherwise.
Returns | |
---|---|
Type | Description |
Schema |
getSchemaUpdateOptions()
public abstract 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> |
getTimePartitioning()
public abstract TimePartitioning getTimePartitioning()
Returns the time partitioning specification defined for the destination table.
Returns | |
---|---|
Type | Description |

getUseAvroLogicalTypes()
public abstract Boolean getUseAvroLogicalTypes()
Returns True/False. Indicates whether the logical type is interpreted.
Returns | |
---|---|
Type | Description |

getWriteDisposition()
public abstract JobInfo.WriteDisposition getWriteDisposition()
Returns the action that should occur if the destination table already exists. See Also: Write Disposition
Returns | |
---|---|
Type | Description |
JobInfo.WriteDisposition |
ignoreUnknownValues()
public abstract 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.
