Interface LoadConfiguration.Builder

    • Method Detail

      • setFormatOptions

        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

      • setNullMarker

        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.

      • setMaxBadRecords

        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.

      • setSchema

        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).

      • setIgnoreUnknownValues

        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.

      • setSchemaUpdateOptions

        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.

      • setAutodetect

        LoadConfiguration.Builder setAutodetect​(Boolean autodetect)
        [Experimental] Sets automatic inference of the options and schema for CSV and JSON sources.

      • setUseAvroLogicalTypes

        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.

      • setDecimalTargetTypes

        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.
        Parameters:
        decimalTargetTypes - decimalTargetType or null for none
