public static interface LoadConfiguration.Builder
Methods
build()
public abstract LoadConfiguration build()
Returns
setAutodetect(Boolean autodetect)
public abstract LoadConfiguration.Builder setAutodetect(Boolean autodetect)
[Experimental] Sets automatic inference of the options and schema for CSV and JSON sources.
setClustering(Clustering clustering)
public abstract LoadConfiguration.Builder setClustering(Clustering clustering)
Sets the clustering specification for the destination table.
setCreateDisposition(JobInfo.CreateDisposition createDisposition)
public abstract LoadConfiguration.Builder setCreateDisposition(JobInfo.CreateDisposition createDisposition)
Parameter
Returns
setDecimalTargetTypes(List<String> decimalTargetTypes)
public abstract LoadConfiguration.Builder setDecimalTargetTypes(List<String> decimalTargetTypes)
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.
| Name | Description |
| decimalTargetTypes | List<String>
decimalTargetType or null for none
|
Returns
setDestinationEncryptionConfiguration(EncryptionConfiguration encryptionConfiguration)
public abstract LoadConfiguration.Builder setDestinationEncryptionConfiguration(EncryptionConfiguration encryptionConfiguration)
Parameter
Returns
setDestinationTable(TableId destinationTable)
public abstract LoadConfiguration.Builder setDestinationTable(TableId destinationTable)
Sets the destination table to load the data into.
| Name | Description |
| destinationTable | TableId
|
Returns
public abstract LoadConfiguration.Builder setFormatOptions(FormatOptions formatOptions)
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
setIgnoreUnknownValues(Boolean ignoreUnknownValues)
public abstract LoadConfiguration.Builder setIgnoreUnknownValues(Boolean ignoreUnknownValues)
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.
| Name | Description |
| ignoreUnknownValues | Boolean
|
Returns
setMaxBadRecords(Integer maxBadRecords)
public abstract LoadConfiguration.Builder setMaxBadRecords(Integer maxBadRecords)
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.
| Name | Description |
| maxBadRecords | Integer
|
Returns
setNullMarker(String nullMarker)
public abstract LoadConfiguration.Builder setNullMarker(String nullMarker)
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.
| Name | Description |
| nullMarker | String
|
Returns
setSchema(Schema schema)
public abstract LoadConfiguration.Builder setSchema(Schema schema)
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).
setSchemaUpdateOptions(List<JobInfo.SchemaUpdateOption> schemaUpdateOptions)
public abstract LoadConfiguration.Builder setSchemaUpdateOptions(List<JobInfo.SchemaUpdateOption> schemaUpdateOptions)
[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.
setTimePartitioning(TimePartitioning timePartitioning)
public abstract LoadConfiguration.Builder setTimePartitioning(TimePartitioning timePartitioning)
Sets the time partitioning specification for the destination table.
setUseAvroLogicalTypes(Boolean useAvroLogicalTypes)
public abstract LoadConfiguration.Builder setUseAvroLogicalTypes(Boolean useAvroLogicalTypes)
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.
| Name | Description |
| useAvroLogicalTypes | Boolean
|
Returns
setWriteDisposition(JobInfo.WriteDisposition writeDisposition)
public abstract LoadConfiguration.Builder setWriteDisposition(JobInfo.WriteDisposition writeDisposition)
Sets the action that should occur if the destination table already exists.
